I'm too busy dealing with my own shit without being concerned with what consenting adults do.

MotherOfCrocodiles · 09/03/2025 22:38

Half your age +7.

So no one under 20 for a 26yo

DearDenimEagle · 09/03/2025 22:40

Nope. I was 17 and dated guys in their mid 20s . When I was 18 I moved in with a 24 yr old, married at 19 , mother at 20 Divorced 20 years later. My friend, male, aged 20, married a divorcee (with children) aged 30 and they’re still together 30 years on. My 29 yr old grandfather married my 16 yr old grandmother…she chased him for his money, and he adored her all his life. Died in his mid 90s. What people do is up to them once they are adults.

My son is 18. I would be very alarmed if he was sleeping with a 26 year old. He’s still at school!

WysiWyg40 · 09/03/2025 22:41

When I was 17 I was dating another 17 year old and we worked in the same place .
I had also befriended a 36 year old single mum who also worked at the same place .
I found out he was seeing me of an evening ( we were not sleeping together ) but then going around the other co workers house and they were sleeping together .
All a bit grim . I left them to it .

SprinkleOfSunak · 09/03/2025 22:43

Good luck to them, let them enjoy themselves.

GrantMitchell · 09/03/2025 22:44

When I was in my late 20s, a friend’s flatmate kept hitting on me. He was funny, interesting and handsome. He was only 18 though and I couldn’t get past that so I didn’t get involved with him.

ItGhoul · 09/03/2025 22:45

No. They’re two adults having sex. Nothing to judge.

Odd that some people are saying ‘How they would even be moving in the same circles’ and ‘An 18-year-old is basically a child’. How do you square that with the fact that lots of 18-year-olds are working full time as equals alongside other adults of all ages, then? When I was 18-19 I was working alongside (and managing!) people in their 20s, 30s and 40s. We all interacted and socialised as adults because that’s what we were.

Id just wonder why she set her sights so low. 18 year old boys don't even have their full brains yet!

It's not his brain she's interested in.

BIossomtoes · 09/03/2025 21:45

They’ve been together for 34 years and not only are you still judging them but you’ve encouraged your children to do the same? It’s about time you got over it, don’t you think?

Why should she? Her mother was sleeping with a child, hers sons age and friend, and moved him in with her children. Why the fuck should anyone get over it? It doesn't get any less revolting because they're older now and still together.

Purplebeach · 09/03/2025 22:48

Like pp have said it’s not the 8 year gap but the fact one is a teenager that makes it inappropriate.

DoYouReally · 09/03/2025 22:49

Yes I would.

Life stages are too far apart to be an equal situation.

I briefly date a 27 year old when I was 18. I did so but choice snd saw nothing bring with it. Looking back there was a hell of alot wrong.

TonightWithTrevorMcDonald · 09/03/2025 22:49

Typical hypocrisy in these replies.

Hankunamatata · 09/03/2025 21:57

Depends on the people. Some 18 yr old could be very venerable

It's "hakuna matata" (not hankuna) 😊

Firefly1987 · 09/03/2025 22:50

I think it's ironic because if a poster was having trouble with their 18 year old son most posters would say he's an adult kick him out and let him fend for himself yet at the same time expect to have a say in what their 18 year old (or any 18 year old for that matter) does in their sex life? I wouldn't have been interested in an 18 year old at 26 but my dad was 27 dating my mum at the same age and they were married over 40 years. I know things are different now but people really pick and choose when an 18 year old is an adult and when they're not...

Bully for you. My 18 year old boy goes to school everyday in his school uniform.

CountingDownToSummer · 09/03/2025 22:51

On the brief info you have given yes I think I would

Becs258 · 09/03/2025 22:53

No. I was ‘that woman’. Had been friends with the 18 year old through a shared hobby. Feelings brewed over a number of months. 25 years later we’re still very happily married.

BrillantBriony · 09/03/2025 22:53

er yes…

Is the age of consent now for those over 20?

A Teenager is just someone who has an age with the number ending in 'teen'. What does that mean in actual fact?

Is someone who is 20 suddenly very very different to someone who is 19?

He's an adult, 2 years over the age of consent, as long as she hasnt been his teacher or lecturer or something then its for them to decide.

I dated someone ten years older than me when I was seventeen. I don't understand why people judge so much.
They are both adults and can do what they want. It sounds like it's just a bit of fun for both of them so what's the problem?

I agree!
I dated a guy who was 28 when I was 18 and thought nothing of it...didn't even cross my mind that people would view it as 'eww' or 'inappropriate'.
My mother wasn't keen on the age gap, but then my mother made it her life's mission to hate absolutely everyone I ever dated no matter what their age! (including my now DH!)
We went out for about 18 months and the age gap wasn't the reason we eventually drifted apart.

SheridansPortSalut · 09/03/2025 22:57

Yes.

SheridansPortSalut · 09/03/2025 22:58

My sons were still in school at 18.

If they came home with a 26 yo mum of two I'd have had a lot to say about it.

Time40 · 09/03/2025 22:59

No, I wouldn't. They're both adults - and both quite young. It's not a massive age gap.

TheGoogleMum · 09/03/2025 22:59

I like the half age +7 is minimum socially acceptable dating age rule. I think it works here, 18 is a little too young
