Not to have known his true age before sleeping together?

He’s bloody 18! Not 19 until April

Casual conversation and flirting lead to hotel room and sex.

Really mortified to discover he is actually 18. No, he didn’t actually tell me. I assumed he was about 21. I am 28.

I feel so, so awful. Really panicked when I found out the morning after. He doesn’t seem bothered and thinks it’s all fine. Grinning like a Cheshire ca

Good lord, I haven’t scarred him for life, have I? Please someone assure me I’m not sick in the head

I would be furious if I was his mum!

Ick.

Why didn’t you ask? And look for proof?

What age are you?

Edited

What do you ask for? He probably doesn't have a driving license. GCSE certificates 😅 as if we go round asking potential partners for ID.

I couldn’t deal with this. At 28 even thinking he is 21 wouldn’t sit right with me.

Why exactly??

PigletInABlanketJohn · 21/12/2025 03:37

I'll ask President Macron.

Sugarfish · 21/12/2025 02:55

Oh I wouldn’t worry. To me at 28 you’re practically a baby yourself at that age. Just have some fun!

Look for proof....?

'HI, I know it seems a little crazy, but ... I always like to check the drivers license of the person I'm about to sleep with..?

'Birth Certificate?'

None of those? Hmmm...(Thinks) 'How much time would you say you spent on TikTok? Have you ever voted? What memories of the London Olympics do you have?

I mean come on....

OP You've done nothing wrong, and that guy will remember you forever...in a good way...

And you are equally approving of a 28 year old guy having a ons with an 18 year old woman?

Would he be a a " happy memory" to her dying day?

Mine will be.

coconutchocolatecream · 21/12/2025 02:22

I never understand the feelings of disgust this type of thing elicits from some, especially when it's age difference of 10 years or less. Whether the older party is male or female, if it's within legal limits and both consent (and neither are cheating), I simply can't care that much. If you're honestly bothered, ask for ID next time.

One of my sons was 'picked up' in a club at 18yo. I think he rounded up and she rounded down, but next morning she had an attack of the guilts and admitted she was 40 and married with children.

I can assure you it is not a lifelong happy memory for him!

I was extremely unimpressed with both of them but especially her. He'd been in school uniform a few hours earlier!

So they both lied about their age.Hmm that’s convenient for him, it’s not a lifelong happy memory for him now, well maybe he shouldn’t have lied then, clearly he suspected, she was much older than him if she was indeed 40.

If it was a 28 year old man sleeping with an 18 year old girl would the responses be the same?

What are you expecting the responses to be, whether you agree, or not, he’s an adult.
To clarify there’s a 10 year age gap, as l’m sure you already know, there are plenty of older men, who have sex, with much younger women, young enough to be their daughters actually, so therefore, why would there be judgment here🙄

SexyFrenchDepression · 21/12/2025 02:06

I can't imagine finding an 18 yo man attractive at 28, I didnt even find them attractive when I was 16/17 and wpuld have gone for 28+ yo old at that age. Obviously legally nothing wrong but any MN thread about the other way round has very different answers.

How does it keep changing?

As I said I’ve worked with sex offenders for over 10 years.

I also had sex when I was under 16 but never reported it.

My advice to everyone - be careful when having sex with people who you don’t know their true age.

It was obvious what your post meant about being U18 in clubs. I have done much the same.

I personally know 2 people convicted, one was fairly high profile, they had a relationship with a 15 yo, she had lied abiut age but he continued things once he knew (consensual but her parents decided they didnt like it when he ended things) and the other person met her in a pub (ons) and her parents reported him when they found out, this was over 50 years ago, he was only 19 but it was on his record and I knew of it due to his police checks for work.

17 would still have been legal.

This reminds of the storyline in Friends where Monica thought she was dating a college senior....He was a senior all right. In high school! So she thought he was 21 or 22 when he was in fact 17 or 18 - I believe he turned out to be 17. It was sort of funny, but not really.

I thought of that storyline immediately I started reading OP's post! It is very similar!

LBFseBrom · 21/12/2025 01:49

TeaRoseTallulah · 20/12/2025 22:12

Even if he was 19 I think 28 is too old even if it is legal.

Maybe so but the op didn't know he was only eighteen, thought he was older. There's no need to make her feel worse than she already does. She isn't a child molester and isn't going to do it again.

Skippydoodle · 21/12/2025 00:56

tartyflette · 20/12/2025 22:07

Well, he is already an adult, so...
And his Mum is not your problem. I doubt very much that he's going to tell her.

I’m a mum of an 18 yr old, I would just think , hey ho , off you go. Please don’t worry about it

Have you been watching Young Sheldon? It’s a plot line in Season Five.

Georgie was 17 though which i think was under the age of consent for Texas. But they got married etc

DahlsChickenz · 21/12/2025 00:07

I doubt he's scarred for life but it is weird for 28 year olds to sleep with teenagers. Even if he was 19 it would still be weird. He's of the age of consent so you aren't in legal difficulty, but don't teens seem very young to you? When I was 28, sex with a 19 (or actually 18) year old would have felt predatory and deeply unappealing.

I mean it would be weird to pick up a teenage boy dressed in his uniform at say Tescos. Or outside a school.

but a young man dressed up at your usual town nightclub (assuming it’s not student night but even then they are all legal) wouldn’t strike me as someone I needed to demand prove of age from.

Zov · 20/12/2025 23:02

I agree with the posters saying even 21 and 28 is icky. But you've not broken any laws, so what's your problem? Confused

Well, here's a big ick for you. I married my DH when he was 21 and I was 31.

Honestly, some of you are just ridiculously prudish.

Tooobvious · 21/12/2025 00:07

But eighteen and a half isn’t really very far off "about 21", is it?

Well you lucked out didn't you? He could just as easily have been 17. Next time check.

It would still have been legal 🤷‍♀️

NewNameforThisPost2025 · 21/12/2025 00:05

18 is OK. He's an adult.

But this trope of teenage boys (not adults) wanting an older woman isn't always true. Rod Stewart was seduced by a much older woman when he was 16, and the resulting song - Maggie May - makes it clear that this was not a positive experience.

She said she works in the prison service and has met them through her professional role

Only after I and others pointed out that her story didnt line up. Then she claimed to work with sex offenders. Originally she implied that she knew "loads" of men who had been sent down through her own sex life as an underage teen.

Dontlletmedownbruce · 21/12/2025 00:00

I don't think its a big deal OP and I don't understand why people get so bothered about age gaps, whichever way it goes. What really annoys me is the constant assumption young women are too stupid to know their own minds and make their own decisions. The laws are there to protect vulnerable teens from predators. Most women are not vulnerable and are well able to manage themselves, yet we constantly undermine them.

ABeerInTheSunshineMakesMeHappy · 20/12/2025 23:56

Zov · 20/12/2025 23:24

So if you never reported anyone, who are all these men you know who had sex with underage girls and went to prison for it? You said you know LOADS...
