To not want my partner to be an anonymous sperm donor?

We’ve been together a few years, own a home together and I’m in my 2nd trimester of pregnancy.

Early in our relationship my partner told me he was considering doing sperm donation for a bit of pocket money/fun money. He had a holiday coming up at the time and wanted some spends. He had decided to ask my opinion before going ahead with it which I really appreciated as we were aiming for a long-term relationship at the time. I said I wasn’t personally comfortable with it as it felt like a huge thing to be doing just for some pocket money. I also was quite honest and open by the fact that the thought of a load of other women being pregnant with his offspring was weird to me and would put a dampener on the relationship. He understood and binned off the idea.

His best friend who is a single man and doesn’t plan on having his own kids (he spends half the year in Thailand and loves the bachelor life) has recently donated sperm and has been encouraging my partner to do it. Both on the basis of a bit of extra money and to “help people”. My partner has slowly been coming around to the idea and has mentioned to me he’d like to look into an anonymous donation again.

I told him I wasn’t comfortable with it. I don’t want to worry about my child having random siblings everywhere. I don’t want any random strangers who resemble my partner joining us for Sunday dinner in 18 years expecting him to step up and be their dad. And then on a slightly more unreasonable note - I don’t like the idea of other women being pregnant with his baby! I’m not usually a possessively jealous type and I know it’s very common to have children with more than one person and that’s normal nowadays. But I am otherwise in a really happy relationship with him and I feel like having children by him should be something that only I get the “privilege” of whilst we’re in a relationship? I don’t know if that makes sense. I think that’s a relatively normal thing to feel whilst pregnant isn’t it? If he had an older child with an ex partner it’d be different of course but the thought of other women being pregnant by him whilst I’m raising his newborn…it just freaks me out even though no cheating would’ve occurred. It just feels so wrong on a primal level. Maybe I’m just hormonal, I don’t know. I can understand people like his mate being donors but I don’t get why you’d do it if you have your own famil.

He hasn’t been nasty about my feelings but says I’m being overly sensitive about the emotional aspect of it and he doesn’t see why I’d feel jealousy towards any women that end up the recipient of his sperm. He also says the extra money will be useful for stuff for our baby. He says he’ll consider my feelings but that he will still go ahead with it if he wants too whether I like it or not.

I just hate hate hate the whole idea of it and I am so angry that he wants to risk upsetting me and bringing a load of resentment into our relationship for the sake of a few hundred quid (maximum).

And if he really likes the child? Or a daughter is a real beauty or a son is a chip off the old block? How can he possibly know how he would react to potential children that are his but not yours? I sort of get he thinks it will not impact him or your family but it might.

Yes and if he really likes the child, what if he also really likes the mum and she just happens to be single. Would worry he may jump ship into a different family.
I don't have anything against sperms donation, but the way he is going about the idea isn't right. It should be a joint decision.

Sesame2011 · 30/03/2026 20:03

If he ks donating in the UK legally he will not be paid for it. If he's getting paid he's either doing it abroad or via Facebook etc.

I wonder if he is planning on going to Thailand to do it as his friend lives there p/t.Not sure if they get paid there.

SadTimesInFife · 31/03/2026 06:35

He's a wanker...

OnlyMabelInTheBuilding · 31/03/2026 05:17

I don’t understand why anyone in a relationship would do this, now that it can’t be anonymous. Would be a dealbreaker for me too, basically waiting for the door to ring in 18 years with another child he proactively created. No thanks.

It's only easy to come by because men give it away so readily instead of realising that their sperm is basically the only thing women need men for in this day and age (to be extremely cynical) if there suddenly was a shortage of it women would be paying top dollar all of a sudden. Any man who wants to give it away for peanuts is dumb as rocks!

We do pay top dollar… to the sperm banks, not the donor

Dliplop · 31/03/2026 03:12

This is a dealbreaker. My husband, father of my kids is a sperm donor. Not for money. It was important to him and I do think sperm donation was great, but I have my boundaries and he’s respected them (our was the last new family for him, but he did contribute for siblings to other families around the same time).

So I’m pretty comfortable with it and happy for those families. BUT when our family was done, I needed him not to donate ever again. In your case, as you are starting your family you know it’s now a boundary for you. So he either needs to just not do it, or you dump him.

I would discourage this 'best friend ' :

'His best friend who is a single man and doesn’t plan on having his own kids (he spends half the year in Thailand and loves the bachelor life) has recently donated sperm and has been encouraging my partner to do it. Both on the basis of a bit of extra money and to “help people”.'

He sounds VERY unsavoury!

ImDoneOnceAndForAll2 · 31/03/2026 03:05

BamBamPadam · 30/03/2026 19:57

Yes we are and I have mentioned this to him and he says he wouldn’t mind a superficial relationship with the offspring but he wouldn’t let them inherit anything or impose on our family life. He’d maybe just see them on his own occasionally if any of them ever got in touch

The child / children can contest the will

Your child could get into a relationship with the other child and have a baby of their own, that would be my concern

Willowywisp · 31/03/2026 02:54

BamBamPadam · 30/03/2026 20:07

Yes we are! Don’t think he’s even bothered to look into it that seriously and research the practicalities of it as I just mentioned to him that I was “researching” online and found it was only expenses paid and he seemed slightly shocked. Which almost pisses me off even more. Stressing me out just for the sake of it rather than thinking it’d genuinely financially benefit us. I think the thought of donating sperm just makes him feel special or something, ugh.

i know the mate donated in another country which he has strong connections with and not the UK

Edited

What's so special about him that makes him believe anyone would choose his sperm?

Jhm88 · 31/03/2026 02:46

My money is on breeding fetish. And his best friend who spends half the time in Thailand is probably into some grim things as well.

blenny23 · 31/03/2026 02:38

Honestly, I would feel exactly the same way as you.

And what would also bother me is the possibility that my child might inadvertently end up dating a half sibling some day. It can and does happen - people have been married for years and had kids together before finding out they’re actually related.

Obviously the chances are small, but you never know, do you!

My best friend has donated sperm in the past but he’s gay and has absolutely no plans to have a child of his own within his relationship. So I completely understand why he has donated.He has said he’d be willing to meet any child of his when they get his information at 18 but isn’t interested in being a ‘dad’ himself.

I’d feel sick at the thought of someone else being pregnant with my partner’s child whilst I was in a relationship with them. I’m sure some people couldn’t care less but it just wouldn’t sit right with me. The fact your partner basically has a complete disregard for your feelings about this is such a huge red flag. And his best mate needs to p* off quite frankly!

GreenCaterpillarOnALeaf · 31/03/2026 01:59

No fucking way. Also I would probably not trust him. It’s so easy to do it in secret, even the convos you’ve mentioned would put me off.

I don't know if someone else has mentioned this but my mind immediately went to the Quiverfull movement 🥺.

There's a world of difference between a broke single student making a bit of pin money and whatever the f*CK this 👆 is.

I had to Google that, where the hell do people hear about this stuff 🙈😂

Shatandfattered · 31/03/2026 01:27

Uhm, I'm pro choice and I was just about to say his body his choice, if a woman came on here saying she wanted to donate her eggs she'd be hailed and told don't let anyone dictate what you do with your body. If a woman wants to abort and the man is furious tough, her body her choice springs to mind in those situations.

That being said his reason is ridiculous, it's very immature American teen comedy where the college boys have to scramble for cash and go to a sperm bank. A woman would do it much more from an altruistic perspective. That's a huge assumption from me and I certainly don't know statistics but I feel women are more likely to donate her eggs from an empathetic place not I want £50 and to spread my seed.

Side note I didn't know breeding kinks were a thing, is that what that crazy fertility doc guy was about then? 😯

Just like women keep on saying about their bodies especially when pregnant his body his choice

WaltzingWaters · 31/03/2026 01:08

The fact he’s even considering it when you’ve made your feelings about it clear is really awful. Made a million times worse by the fact he’s waited until you’re “trapped” by pregnancy to bring this up again.
Id be seriously reconsidering this relationship. He sounds like a clueless, disgusting, selfish prick.

His body his choice..

Do you feel ill at the thought of one of the female members of your family killing an unborn baby by having an abortion?

Oh FFS the pro-lifers have crawled out the woodwork.

ArtAngel · 31/03/2026 00:58

You wouldn’t physically be able to proctreste with two men at the same time.

He is threatening to procreate with many women while you are pregnant.

Because he is a man and biologically can.

So taking advantage of his biology and reproductive privilege.

Misogynist twat.

Mackerelfillets · 31/03/2026 00:55

Are you super sure its anonymous? I got the impression kids were allowed to find out where they came from. They could very easily sign up to a DNA website and find relatives. My adopted son found cousins on ancestory.

Saladbrains · 31/03/2026 00:54

BamBamPadam · 30/03/2026 19:59

I actually think it would be a dealbreaker for me, the thought of it makes me feel ill

This is truly horrible. He is saying ‘fuck you, I will biologically father children alongside yours and give our baby bio half siblings because I want to”

YANBU OP.

His horrible sexual-tourist mate is disgusting, the pair of them clearly think having paying for sex with women buys consent and getting paid for wanking means nothing and that paternity has no connection to family love.

He will deign to take your feelings into account but impregnate other women if he feels like it… who the fuck does the emotionally abusive patronising misogynist twat think he is??

(I am upset and angry on your behalf)

sittingonabeach · 31/03/2026 00:53

Isn’t that one of the reasons that they limit the number of children from an individual sperm donor (in the more regulated countries) @Bigcat25

DaisyChain505 · 31/03/2026 00:52

Sounds more like he gets a kick out of the idea of spreading his seed everywhere rather than the financial gain.

Bigcat25 · 31/03/2026 00:49

Pistachiocake · 30/03/2026 23:51

I believe so, but a lot of people worry about their child meeting someone at, say, 16, when they don't know, and it turning out to be a sibling. I guess we have all heard the stories of someone being attracted to a sibling (when they don't know they are related, obviously). I think it's called GSA, and was once a reason why people didn't approve of having casual sex-because children brought up with their siblings, as would have been the norm, do not suffer from this. Obviously sperm donation is a modern variant of the issue. OP, I agree, I would never be ok with someone having a baby with a stranger. Being a surrogate for a sister is one thing-getting a stranger pregnant (even without sex), and never knowing how or if that baby will be cared for, or if they might meet your daughter at college one day-no.

That is an incredibly low probability.
