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.

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

Mumsnet doesn’t approve of age gap relationships…

TheKittenswithMittens · 06/06/2026 12:51

These acronyms. I thought BF was a boyfriend. So I am thinking she already has a boyfriend. So what does he make of it? Then I read on and thought but he has a boyfriend as well.

Justyouwaitandseeagain · 06/06/2026 12:50

I think the strangest thing here is her responses. But if she is actively looking for sex rather than commitment then her replies make more sense. I would focus more on helping her establish safe boundaries rather than worry about particular men she is meeting up with.

OonaStubbs · 06/06/2026 12:50

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

If that’s what she wants, it’s a bit rich to be blaming the man for potentially only being interested for sex.

Scenario number 2 is the one I am most concerned about. I'd be less concerned if he admitted all he wanted was sex, and she wanted the same thing. She thinks he wants a relationship, and she seems open to the idea, although not as on board with the idea of anything long-term as she thinks he is.

Oh no 😟 Your DD sounds vulnerable and he sounds like a potential predator (I don’t mean child predator as yes, OP’s DD is an adult but he sounds like a predatory man in general)

Wishimaywishimight · 06/06/2026 12:47

"Would you like to go for dinner?". "I'm on my period." What a bizarre response!

Crazykatie · 06/06/2026 12:46

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

Maybe not but reverse the roles, there are many reasons why a 22 yr old would be interested in a 40yr old man, not least of all, money and maturity.

One of my nephews - 42 married a girl 21, he was a very good catch, they got on well enough at first, now they live more or less separate lives but she wears the trousers, no kids - her choice. It suits her to be Mrs XXX he funds her lifestyle, seems to suit him.

Sex is the reason. It’s the only reason men have for doing anything. I’m not slagging them, but it’s their main motivation in my experience.
That’s the reason. Sex.

So the only reason men do absolutely anything is for sex?
My male partner has looked after me through serious illness, was that just for sex?
He works 12 hour shifts. Is that just for sex?
He looks after his elderly parent. Is that just for sex?
You have clearly had some bad experiences.

Sgreenpy · 06/06/2026 12:43

Both people are adults.
The end.

summermidnightsun · 06/06/2026 12:43

Gross. At her age I saw men older than 25-26 as too old and creepy. Now I’m mid 30s, I see 22 year olds as a different generation and feel old among them, I don’t always understand the new slang/lingo etc.

mjhx · 06/06/2026 12:42

I was with someone who was 27 and I was 17.
You are absolutely correct in my experience.
Although not the same age gap I wouldn't allow this with my daughter 😩

She's not diagnosed with SEN. I'm not worried about her being pressured into sex she isn't comfortable with; she's capable of asserting herself in that way

She is looking for sex rather than commitment, as far as I can tell, although she's not said that outright to me (but who would admit that to their mum?). As her mum, I hate this, but she is a consenting adult, and she is able to give informed consent. She seems to be after a friends-with-benefits type arrangement.

If that’s what she wants, it’s a bit rich to be blaming the man for potentially only being interested for sex.

I dated a guy of 44 when I was 21. We were together for 3-4 years in a mostly successful relationship. We had great sex (for both of us) and genuinely laughed a lot together. In retrospect he wasn’t a particularly grown up 44 year old but, even in my early 20’s I was not a woman to be controlled.

I won’t deny that he treated me badly at the end of our relationship but he didn’t get away with it for long and I called time on him. We were great friends for a number of years afterwards and I leant on him after my next “heartbreak”

Edited to add that in the beginning of our relationship it was me that pursued him.

ScullyD · 06/06/2026 12:38

At 22 I have to say I would never have gone for a guy in their 40s for FWB. She surely has more in common with guys her age and frankly the 20s guys are usually hotter too.

I did sleep with an older guy once but to make it a regular thing? No chance. Also no one is saying the man is a pervert without knowing him but some of us are speaking through the lens of wisdom and experience.

Berlinlover · 06/06/2026 12:33

YABU Your daughter is a grown woman but since MN absolutely hates age gap relationships the majority here will think this man is some sort of pervert. The whole thing about “warning” him she’s on her period is very strange though and what’s even stranger is your daughter telling her mother all this.

She hasn’t ’raised sex’. She’s told him that she’s on her period because she’s worried that that’s what he’s after.

I didn’t say that she was a child, I said that there is a huge maturity gap between someone in their early 20s and someone in their 40s. Mentally, a 22 year old isn’t much different to a teenager.

Of course he's probably after sex. Just as she probably is, as a 22 year old woman.

mixandmatch · 06/06/2026 12:31

I would also be concerned but she’s a grown woman and I can fully imagine deciding to sleep with a 40-year-old man when I was her age, if I was attracted to him and/or felt we had loads in common.

I know two couples with 15-year age gaps who have been happily married for years. Admittedly they met IRL not online but the world has changed and I think you need to give some gentle advice, then stay out of it.

He actively wants someone young, less experienced and established, and more easily influenced, so that he can groom her into being his ideal, subservient partner, and begin a lifetime of abuse.

Dramatic much?

Not at all dramatic. And abuse comes in many forms.
Happened to me, although I was 22 and he was only 31.
Took me ten years and two kids to realise, once I'd properly grown up.
And another 15 to leave.

SpottyAlpaca · 06/06/2026 12:29

It’s just basic evolutionary biology and the result of thousands of generations of human sexual selection.

The reason a 40 year old man might be interested in a 22 year old woman is blatantly obvious. Sex. He wants to shag a young hottie at the peak of her physical attractiveness.

It works exactly the same way in reverse, of course, for reasons that are also blatantly obvious. Money. Hot young women are attracted to older, much wealthier men because they can provide access to plentiful resources for her and her future children.

Dollymylove · 06/06/2026 12:29

Try not being so invested in your 22 year old DDs sex life. Shes a grown adult and can make her own decisions. You might not like those decisions but they are hers to make.
She will learn .....

MidnightMeltdown · 06/06/2026 12:28

SplendidUtterly · 06/06/2026 12:15

Why on earth did she feel the need to tell him she was on her period?

Because she’s 22, not 32, and has virtually no adult life experience. This is why she shouldn’t be dating a 40 year old man. They still think like teenagers at this age.

Maybe, I thought she sounded ‘young for her age’.

ScullyD · 06/06/2026 12:28

I’m early 30s now, no way a man in his 40s would’ve turned my head ten years ago.

I think your DD sounds vulnerable to being misused by this guy purely because she told him she has her period. There is no reason to give out this kind of detailed private info so soon.

Our brains don’t finish fully growing until 25. I had a boyfriend who was near 30 at 22 and that was bad enough. Why? Because he was sexually pushy and because he wanted to push all his fully formed ideas on the world onto me when I was still just figuring out who I was.
