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!

Exactly! No way you had no idea.

Not necessarily in my experience!

BeMellowAquaSquid · 20/12/2025 22:51

I don’t think I’ve ever I.D’d a conquest before now.

Pathetic.

t'is no problem.

Older men with younger women do not seem a problem.

Older women with younger men are. Just misogenistic,

Mine is 20 years younger. Nobody cares. Not one of our friends.

Is this some sort of poem?

18 year old boys very much much look like boys. There's a big difference between an 18 year old boy and a 21 year old man, there can be no mistaking it.

How old are you? I wonder whether those who have been mothers of 18yr olds see the boy that younger women wouldn’t notice.

They really all don't. My DS had a full beard and could easily buy alcohol from age 15. Now at 21 he never gets ID'd, whereas my 28 yo married DD does all the time. Everyone is different

My mum met my dad when she was 17 and he 27. 38 years later and they're still together.

Exactly! People are saying there is an ‘Ick’ factor when it’s the other 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?

I slept with a 28 year old man when I was 18- I was on my gap year and I totally initiated it. I found his maturity and confidence really sexy. It was just a thing for a few days because we were off to different places on our travels but it is still a happy memory for me 20 years later. They are both adults, I don't think anyone needs to feel guilty.

SunMoonandChocolate · 20/12/2025 22:56

I really don't understand what all the fuss is about. All this shit about an 18 year old boy looking like a boy, etc. and you must have known. Who actually cares? You are both over the age of consent.

I'm more surprised that you enjoyed it, as at 18 he may not have been that experienced, but rest assured, he will ALWAYS remember the gorgeous older woman that he shagged when he was only 18, and when you're an old lady like me, you can shock your grandkids by telling them about going to bed with a toy boy, when you were 28.😆

I bet he thought Christmas had come early.

You have made a young man very happy op.

Sorry but how do you know this ?

Are you assuming every man is so desperate to have sex that they have so little discrimination every sexual encounter must be a positive experience?

Perhaps he went home feeling grossed out by being taken advantage of by an older woman?

You have no way of knowing how this guy felt.

Some of the attitude on this thread are absolutely toe curling in their assumptions.

Ick.

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

What age are you?

Edited

She's 28. Paragraph three of the OP.

It would be perfectly fine for a 28 year old man to have a one night stand with an 18 year old woman.

Give over hes 18 not 12. He'll probably have a big grin on his face for weeks and his friends will be as jealous as hell 🤣🤣

Some posters don't seem to understand that a paragraph can have more than one sentence in it.

PyongyangKipperbang · 20/12/2025 22:59

A ONS between two consenting adults....dont see the issue.

If there was a power imbalance then yes there would be, that why people have issues with much older men with younger women as the women often dont know how to say no. Or if OP was his boss/teacher etc But that doesnt sound like this is the case here.

Funny thing is that his mates probably wont believe him when he tells this story, so not much to worry about there!

And why would it be worse if he was 17 to the PP who mentioned it? The age of consent in the UK is 16.

Eyeshadow · 20/12/2025 23:00

If I thought someone looked 21 then I’d 100% find out their age first.

Most people look at least a couple years older than what they are - he could have easily been 14/15.

I know so many men in prison because they didn’t find out someone’s age and then they ended up being under 16.

You didn’t do anything illegal but this is a big lesson learnt.

Just because that was your experience doesn't mean every young woman's experience of sex with older men is a positive one.
Many, many young women are exploited by older men.

OP started the thread either because she feels guilty or because she wanted to brag about her experience.
Nobody knows how the young man feels.

Incelebration · 20/12/2025 23:01

In my opinion you've done nothing wrong. It's not illegal, and you didn't intentionally sleep with an 18-year-old.

pinkstripeycat · 20/12/2025 23:02

All the uptight folk, he’s 18 not 15! It’s sex. Not a big deal.

My friends, 14 yr age gap, she older.
My mum was 20 and my dad 37 when they married! Married!

IridiumSky · 20/12/2025 23:02

So what?

MannersAreAll · 20/12/2025 23:02

I know so many men in prison because they didn’t find out someone’s age and then they ended up being under 16.

You know multiple men who have been imprisoned for having sex with someone they believed was over age?

Really?

AD1509 · 20/12/2025 23:02

Quite grim- but not illegal.

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

Christmash · 20/12/2025 23:03

Its really grim but if you honestly didn't know then don't beat yourself up too much.

I don't personally understand wanting to sleep with a 21 yr old at 28 but mayne this is a bit of a lesson to up your minimum age?

Yet I don't know one single man who is in jail for sleeping with an underage girl!

Youraveragelass · 20/12/2025 23:04

I’m surprised you couldn’t tell he was so young. I have siblings the same age, I’m 30 and quite frankly, we are on different planets 😂 literally worlds apart!
