To think there is no genuine reason a 40-year-old man would be interested in a 22-year-old?

DD is online dating again and is messaging with a 40-year-old man. She is utterly convinced that he is interested in her as a person and that he is a genuine man. They like the same music, attend the same concerts, play the same games, and follow the same anime series.

I believe there are only 2 reasons a man this age would be interested in a 22-year-old.

  1. He wants the kudos of bedding a woman in their 20s.

  2. There is something wrong with him, and women his own age are too old and wise to tolerate his bullshit, so he needs to target women too young to know better.

For context, I am 44, and the idea of dating one of DD's mates is horrifying. I like them well enough. I'll happily sit and have a drink with them or a night out with them, but some of the things they say and do are childish and irritating, and I'd sooner gouge out my eyeballs with a rusty spork than be in a committed relationship with one of them.

According to DD, he works full-time and owns his own home, so he is not a basement-dwelling incel.

He wants to take her out for dinner on Monday. She's told him she's on her period, and he says that's fine, they're only going for dinner, and he doesn't want sex with her on their first date. He wants to get to know her. I don't believe him, but it's convinced DD even more that he is genuine.

Yabu.
She's a fully grown adult.
Men generally tend to like younger women. It is what it is. Whether this is right or wrong is not relevant.

You need to get over it.

Fully grown physically maybe but her brain isn’t fully developed for a good few years yet. I can look at someone in their early 20’s and see them as beautiful, but I’m not attracted to them, it feels wrong.

I'd think they were both up for a shag.

"She's told him she's on her period"

What the Hell.???

Aposterhasnoname · 30/06/2026 12:39

My jaw is on the floor here. She told a man she barely knows that she's on her period to head off any idea they will sleep together on the first date?

I am so old. In my day, if anything was suggested, a simple "no, I don't do that" was usually quite enough, and if it wasn't, then it was a handy guide for who to refuse a second date with.

I disagree. I married someone 21 years older. I never felt as though there was any age difference. It was an amazing relationship. We could talk for hours, were constantly laughing, doing the 'silly' things couples do and had mind-blowing sex. We could just sit in silence and snuggle up on the sofa watching TV; we were content and happy. It really was a wonderful relationship. We were a real team and had a brilliant time together. I don't regret a single second of it.

Let them find out if it works for them.

Surely you would want her to be happy?

Life is too short.

What happened?

I'd like to see a sliding scale, similar to what they have in some US states.

Both parties under 15 - should trigger SS involvement, but not a criminal matter.

Both parties 15-17 - Fine.

17 - 19 - Fine.

19 - 25 - Fine.

Above 25, your brain is fully developed, whilst a 50-year-old dating a 25-year-old is gross and likely will result in a power imbalance, the 25-year-old is mature enough to make that choice for themselves.

Under 25, I think the risk of abuse/coercion is too high to ignore. Obviously, I realise this will never happen, as you are, technically, an adult at 18, even though you are not fully developed mentally.

but what about when its the younger one that wants the older person ?

Scarlettpixie · 11/06/2026 18:22

I see the date has now been cancelled. However given your DD was looking for sex I am not sure why this guys motives were being questioned. From what you said, if anything he seemed more interested in a relationship with her - not unreasonable seeing as they get on and have shared interests.

@OonaStubbs It's disgusting and it should not be allowed. And the same applies to older women with younger men. People should date within a reasonable age range and yes it should be the law.

This perspective is ridiculous. The overwhelming majority of men receive very few matches on dating apps. But yet, you want to give an instruction for men to set an artificial restriction so they can't have relationships with an older man or woman, who is their age minus 7, times 2.

For literally no reason other than you want to be annoyed at people, for no reason.

Edited

The only regimes in the world that actually police relationships and punish people for having "wrong" ones are nations like Afghanistan and North Korea.

I don't think they're good role models.

The brain develops past 25, you've bought into a myth based on a study that only used participants up to the age of 25.

Also, the brain continuing to develop doesn't mean that under 25 or any other arbitary age the brain isn't 'working fully' and people can't make appropriate decisions.

The whole "your brain is fully developed by 25" thing is so oversimplified though. Yes your brain continues to develop, sometimes into the 30s even. The idea that your brain is fully cooked at exactly midnight on your 25th birthday is ridiculous and completely ignores the common sense approach that a maturing brain and frontal lobe has as much to do with life experience than simply biological age. Likewise, abuse and coercion is rife in relationships regardless of an age gap. I mean, should you not have been allowed to have children when you did given your brain wasn't developed? There are people in their 30s/40s/50s even with limited relational or life experience and people who have been living independently and are parents by 24. There's a million better ways to educate people about healthy relationships and provide support for anyone being abused than to impose these silly age rules on who grown adults can and cannot choose to have a relationship with.

I know, what does she propose as punishment? Jail time?

I'm wondering how this would be policed, as women in our 30s will we need to report to someone who we're dating and asking permission? 😂

Fancythatfancyhat · 11/06/2026 08:48

You think it should be the law that a 50 year old and 31 year old can't date? Get a grip.

That’s ridiculous. It meant I wouldn’t have been in relationships for a good decade, as I didn’t want silly young men my own age, they were twats. There was never a power imbalance in the relationships I was in with older men. People should be free to make choices that work for them.

Don't be ridiculous. It's not disgusting, and the government has no right to be policing relationships like that.

mambojambodothetango · 10/06/2026 22:39

My friend got together with her DH when she was 20 and he was 40. They're happily married nearly 30 years on. We all thought it was weird at the time but it has worked for them.

shuggles · 06/06/2026 21:31

@OonaStubbs I will say it again, the "Half your age plus 7" rule should be enshrined into law. It would solve so many problems.

Why should there be a restriction on a 50 year old woman to have a relationship with a man younger than 32? Is it right to control women in that manner?

Jay99245 · 10/06/2026 17:52

You’re right to be concerned.. last one of those I knew, who was only interested in young women, had a decent job, a nice car, his own home, turned out to be a rapist and is currently serving time in prison.
Of course it might just be a coincidence that they like all the same stuff and he hasn’t found the right woman, but you’re right to be concerned. Let be honest.. if he’s such a good catch why is he still single? It’s more likely he’s a massive weirdo or sexual predator!

flippertygibbet4 · 09/06/2026 08:24

Does she know anything about him? As in, is he married? How would she feel if she discovered that he was?

Papster · 09/06/2026 01:27

oliviaAustin · 06/06/2026 20:19

And if your latter point is true then why does the term ‘trophy wife’ exist?

Same as sugar daddy does?

busyd4y · 06/06/2026 12:13

I have friends with a similar age gap, they've been married over 25 years and she was about that age when they met

It was at work so not quite the same situation. He hadn't been married before they met and I've never seen anything to suggest he isn't a perfectly normal human

Obviously this is of absolutely no relevance to your daughter, just an anecdote that it can work

Same here.

Men are genetically programmed to want to have sex with young and fertile women; so there is a 'genuine' reason, but whether it is a 'good' reason is quite another issue. The reproductive instinct does not care whether the man and the woman would be happy together, or whether the man would stick around to help raise the children.

Yes there’s an expectation that we’re above our biological instincts and can logicalise our way out of them if we’re clever and moral enough, but I’m not convinced. I think the ‘good men’ who would never look at a 25 year old, only don’t because it isn’t socially acceptable in their circles to do so. As we know, men act very very differently around other women than they do their family/friend groups.

My ex husband was having an affair with a 20 something. I found out, kicked him out and divorced him. This wasn’t the first time he’d played away with a 20 something but convinced me to stay. This year she’s 30 and he’s 60… I find it utterly disgusting. He was bragging to his mates about her, but she’s now stuck with a diabetic, obese narcissist with no money and who is now claiming disability after he got beaten up for getting involved in a big fight! She knew he was married too. She’s also on disability. Me? I ended up with double the equity he got from the house, live in a beautiful area, and have a fantastic job. Karma really hit them! It’s creepy, and it’s vile and there’s zero reason for these old men to be going after such young women other than as a trophy
