To think that a 35 year old man setting his dating range to age 21+ is revolting?

DP friend is in the process of getting divorced. He is actively on the apps, as he hasn’t had sex with his ex wife for 5 years, is pretty desperate. My partner advised him to set his age range from 21 “if all you want is a shag”, and down to 26+ for a relationship.

AIBU to find this gross? 21 year old girls will think a 35 year old man is ancient, no? He seems to think that that’s an acceptable age gap. For context I’m 37.

It is, it's an arbitrary point to say that suddenly people are able to make "adult" decisions. The brain continues to develop through most of your life, through expeince largely, and a 50 year old will in many ways make better decisions and have more insights than a 30 year old.

But we aren't telling people of 30 they aren't competent to make serious decisions about marriage, sex, having kids, or career.

And really, are you going to say that 21 year olds aren't of an age to make those kinds of decisions?

I never said people are suddenly able to make “adult decisions”. I was talking about the actual physical brain stops developing at 25, as in that’s the time most brains have fully developed and this is the age that is mostly recognised as being a fully formed human. You’re talking about making decisions based on experience. I was not talking about that. It would be pretty stupid of me to say that our brains never stop developing when we grow neurons throughout our life.

Completely disagree with you saying a 50 year old will make better decisions and have a better insight in life than a 30 year old. Where is this evidence? Surely it would depend on life experience? I know many 50 year olds who live very sheltered lives and have very limited insight to that of a well cultured 30 year old. Many older people still make stupid decisions.

I don’t think you’ve actually read any of my
previous posts but I said originally a 21 year old is an adult. So yes, there is nothing wrong with two consenting adults having sex. So I suggest you read before banging about how a 50 year old can make better choices than a 30 year old and has more insight because you are frankly wrong.

No - maybe it's not the same but I'm a woman in my 30s and regularly get early 20s men coming on to me. I'm married so wouldn't go there - but these young women are consenting/swiping match so what's the issue?

Probably the age of the haters, to ensure they are not some unfair competition or something 😂

I don't really think about that. Although for many it seems to be because they wouldn't find that interesting, or wouldn't have.

No, it isn’t myth. Where are you getting your information from? Plenty of reputable and highly regarded institutions have wrote articles which have been peer reviewed as well an extensive research on this. I suggest you look into them articles to inform yourself.

So how old should women be before they are able to choose a sexual partner?

Only according to the legal definition which is arbitrary, and based on nothing other than the convenience of creating a divisive line. According to science we aren’t adults until around the age of 30.

People are too hung up on the idea that you magically become an ‘adult’ at 18, and are suddenly way more clued up than you were at 17.

21 is still extremely young. I think it’s gross personally.

Half your age plus 7 should be lower limit for dating apps.

So for a 35 year old. 25 years old should be the lower limit. and 56 the upper.

So 22 for a 30 year old, ok.
37 for a 60 year old though 😅

Smurfette63 · 15/05/2025 17:59

Age is just a number, and if it's not hurting you why let it matter.

Lollipop81 · 15/05/2025 17:59

I’d be more put off by your partners comments about it to be honest.

MidnightMeltdown · 15/05/2025 17:20

FleurDeFleur · 14/05/2025 06:26

No, it's not "revolting". 21+ is adult. They will be consenting. What's the problem?

JohnTheRevelator · 15/05/2025 17:07

A bit of an overreaction I think. If he'd said 16+ I could understand your disgust,but it's not that uncommon for a woman of 21 to go out with a bloke in his mid 30s.

That is a myth. The brain develops endlessly, largely driven by experiences.

The 'brains aren't fully developed until you're 25' thing is one of Mumsnet's most annoying myths and essentially just used by posters who are intent on infantilising and controlling their grown adult children

It’s not a myth at all. It’s a biological fact. Look at any corresponding medical literature.

No for me it’s because I have a daughter and I don’t like the idea of someone a lot older is because it feels sleazy, plus I wouldn’t want her to end up with an old man in her 30’s. Dh and I are in our 40’s, we were very different in our 30’s. I’m not single so it’s not worry about 20yr olds hoovering up all the men either. i’ve known happy age gap relationships but inevitably one starts aging very very fast at some point. I don’t want that for my DD.

What a parent 'wants' for their adult daughter is entirely irrelevant, because the adult daughter is a grown woman and the only thing that matters is what she wants.

If someone doesn't want their 21 year old dating a man 10 years older than her, that's very much just tough shit. You don't get to vet and control other adults' relationships based on what your preference would be. You can feel however you want to feel, but it doesn't mean it gives you any say over your adult child's choice of partner.

Biologically speaking the prefrontal cortex- part of the brain that helps us makes decisions stops developing around 25. But the brain continues to develop until the late 20s. I doubt men would be debating this issue if the roles were reversed.

That is a myth. The brain develops endlessly, largely driven by experiences.

TempestTost · 15/05/2025 13:31

That seems very odd on your part.

I 48, my partner is 61, we were both a decade younger when we became a couple . When I'm 55 he will indeed be in his late 60s. That seems like a pretty normal gap for two middle aged people.Why would you only be willing to date someone within a very few years of your own age, it's not grade school?

KittyEmK · 15/05/2025 12:27

A bit cringe maybe, but not revolting. Everyone in this scenario is a consenting adult. It's obvious why both parties might be attracted to each other.

YearlySubscriptionRenewal · 15/05/2025 11:53

BatchCookBabe · 15/05/2025 09:03

No it's not just up to me. 21 is too young for 35 year old. That's a fact. It's not just 'up to them.' There's a power imbalance and it's weird. What kind of 35 year old goes for someone just 2 years out of their teens FFS?!

You are confusing your opinions with "facts". they are not the same thing I am afraid.

MerlinsBeard1 · 15/05/2025 11:47

XxSideshowAuntSallyx · 15/05/2025 11:41

FFS there's always so many judgemental women on here about age gaps.

21 is an adult, 35 isn't ancient. As far as I'm concerned, unless you're old enough to be their parent (and not some gym slip, teenage parent) what's the issue!

People should just mind their own business and let other people get on with their lives.

I think a lot of women can't bare the idea that men their own age don't find them attractive anymore.

MerlinsBeard1 · 15/05/2025 11:45

AltitudeCheck · 15/05/2025 11:25

I'd be more interested what upper age limit he set. A broad age range either side of his wouldn't necessarily be a concern, targeting only young(er) women would sound a bit creepy to me!

I think the power imbalance is less of an issue when people have met via a dating app, the women are aware of his age and can choose to exclude him/ men his age.

It is generally accepted people get less attractive and energetic as they get older so I don't think it is concerning to not want to date a much older person. A man in his mid 30s is most likely going to want children so he won't be looking at peri/menopausal women. Biology plays a massive factor in why age gap relationships are predominantly older men/younger women.

Its a psychological jealousy.

Op is in no way romantically involved with this man. So she has nothing to lose either way. He is a friend of her partner.

However her brain is going: " a man my age is saying yhat he would be sexually interested in women 14 years younger than me. Does that mean i'm old?

And she gets jealous and angry at the younger women

Which is where OP's post has started from

Edited

Agreed. My DH ex wife was always banging on about my age in a derogatory way. It is plain jealousy.

As for the idea of 'older' women being jealous of the younger women that the older men are dating... WTAF?! 😂 As has been said, why on EARTH would any woman envy another woman with a much older man? Come ON! 😆
