Not to want my young adult son having sex in my house

In my house?

New build. Thin walls.

His girlfriend is lovely (24), and he’s 23, but she has a lot of responsibilities. Last night I heard him say to her that he didn’t have anything on him (context must’ve meant condoms). And she said she didn’t either, both had a little laugh about it.

Heard him say to her ‘I love seeing you as a mum. I don’t mind if this makes that happen’ and off they went on their jolly jiggles! I was mortified. Mortified! As I say, paper thin walls and I was in the middle of texting a friend.

I have been exact in repeating what I heard to see if anyone other parents here would also find quite upsetting/strange and uncomfortable to hear.

AIBU not to want him having sex in my house? Or do I just blatantly make a lot of noise if I can hear them, or knock and say keep it down? Don’t think I’d have it in me to knock!

I cannot say this isn’t partly fuelled by the fact that I’m so worried he’s going to get her pregnant. What a disaster.

What do you think?

His dad sadly passed when he was younger so no other parent to ask about what they think.

Is this appropriate given his age? Feel like it’s such a grey area

He is absolutely entitled to have sex with his girlfriend. You are absolutely entitled not to have your ears invaded by sounds of him having sex with his girlfriend.

I think we’ve strayed off topic here a bit. It’s your house and you can have any rules that you like but if it feels infantilising to tell your 23 year old son that he’s not allowed to have sex in your house then perhaps you could tell him that he is not allowed to have sex that you can hear. It’s called a private life for a reason. I’m sure he wouldn’t want to hear you having sex. He can have sex while you’re out or he can be quiet about it.
My parents admittedly didn’t live in a new build but tiptoeing across the landing for silent sex with my boyfriend (who was being made to sleep in the guest room) worked ok for my early twenties

Sorry but it’s he’s not his.
‘his’ means ‘belongs to him’.

There's always one!

Are you suggesting it’s a good thing to have 4 kids at 24?

And how does being an adult equal being ready to parent? What a thoughtless response, like your DS was suggesting getting a puppy. Children deserve to be born to people who want them, not somebody who wants a shag but just forgot the contraception

You'd need to ask my mum that, but I don't see why it's a problem? She's still with my dad (I'm the oldest) and she did a bloody good job of raising us.

A lot of children are born via accidents and unplanned pregnancies (my DS was) and are very much wanted. The manner of conception doesn't really matter as long as that child is loved. I was 35 when DS was born, before anyone starts.

MeridianB · 23/06/2025 21:42

It’s really OTT that he thought it was a good idea to go on holiday with her and her young child after knowing her for a month.

She is an idiot for agreeing to him meeting her child after a month, regardless of the circumstances.

This has disaster written all over it for one or both of them.

whistlesandbells · 22/06/2025 12:10

This scenario is mind blowing to me. 23 years old living at home, having sex in his bedroom of his mum’s house with a 24 year old girlfriend who already has children and lives an hour away.

Grown adult children treating parent’s home as if they are all flatmates, with absolutely no real responsibilities or experience of independence willing to have a baby. On whose buck, OP?

This is appalling entitlement.

TheKeeperOfTissues · 22/06/2025 12:00

I'm pleased to hear this mum has so far had some boundaries around her child (i hope you changed her name)

The fact your son thought it was appropriate to try and invite himself on this mums holiday with her child after 5 weeks is concerning to me.
Coupled with the conversation you overheard I'd be worried.

I hope you're able to have a conversation with him, but as he wants to shut talks about it down, I'm going to guess he won't take advice from you.
Is there a male role model/relative he trusts that he may listen to?

I hope it works in the future.

He had a few Amazon parcels delivered today. Opened them in front of me. A child’s toy was in one of the boxes. He said it’s for ‘little Phoebe’

I asked him why he has got a present for a child he doesn’t know. He said he knows her through what his GF says about her and knew she’d like it. I said that may be a bit too overbearing, don’t you think?

He told me he didn’t think so, and ties to stop the conversation. I said are you meeting this little girl? He said he was going to just pose as a friend of her mum’s and pick them up from the airport next week. They’re off to Spain tomorrow and he will be picking them up from Luton when they’re back

He said he asked if it might be an idea for him to come? Apparently she shut him down and said no, it was just a break away for her and her DC. He sounded disappointed

No further conversation about the sex noises from me but I want to bring it up soon.

He soumds very immature and needy.
He knows her 5 minutes.
Does he work?
Is he building a career?
Or is having babies with the first woman he meets his ambition?

Don't hesitate to spell it out to him.
He sounds very naive.
Pussy footing around won't help him.
His fantasy bubble needs bursting.

I would say no more hook ups in your house.

As I say, paper thin walls and I was in the middle of texting a friend.

Don't worry - your friend can’t hear your son humping via text.

Sorry but it’s he’s not his.
‘his’ means ‘belongs to him’.

Do you feel better now? 😶‍🌫️

UndermyShoeJoe · 21/06/2025 18:47

Sounds like as another poster says. His the rebound. This isn’t serious. This a chap she feels safe with while she rebuilds her confidence with.

Sad for your son in that sense. But I wouldn’t worry too much as this relationship lasting long.

His what my friend calls a maintenance man. She has no desire to marry or have a long term relationship she wants sex and keeps her Children well away from him, once she feels they are too close she removes from her life. The baby comment may well of been that step that ends them shortly.

Sorry but it’s he’s not his.
‘his’ means ‘belongs to him’.

Holluschickie · 22/06/2025 00:50

Baffled by the number of posters who think it's a good idea for a man to " try for a baby" when he has known his girlfriend for 5 weeks and cannot afford to even rent.

I suppose then they can just go to her house.

But it sounds like they're talking about trying for a baby? Are you worried it's not serious or old enough for that or do you just not like her? Curious about why it would be a disaster, they're not teenagers.

Well seen as he hasn’t met her child at all yet , I’m guessing having a baby together might be a bad move !!!!!
OP has already said she likes her …

SunnySideDeepDown · 21/06/2025 18:17

I’d mention that your heard him and ask him about his plans to become a father over dinner. Where would the baby live as it wouldn’t be in your house.

He needs to wake the fuck up and not get a girl pregnant when he doesn’t even have his own house.

Agree! He sounds like he thinks a baby = a toy or a pet.

I was 23 when I met dh and had a child from a previous relationship where ex cheated. I have been with dh for 15 years married for 10 and with another 2 kids. Im glad I wasn't judged and mil didn't get involved with our relationship. We also knew each other from school. We got engaged after 1 year and had a baby after 3 years. No one got involved and are still happily married.

It doesn’t sound like you stopped using protection 5 weeks in to your relationship with your now husband 🤷‍♀️

I have no judgement on her age. I think a lot of posters are pointing out she’s got a DC so ought to know the consequences of not using protection. It’s the rest of your life, and the life of a child you’ve got to think about. In her case, existing DC as well as any she makes with OP’s DS. Seems needlessly flippant of her to giggle about getting pregnant in this situation.

Treesandsheepeverywhere · 21/06/2025 23:58

No respect for you whatsoever as if they'd walls are thin, he'll know this from hearing you on your phone or such.

Time to move out.

Lilaug · 21/06/2025 23:57

I wouldnt feel comfortable with my child having sex in my home.. You may want to have a nice talk with him that you need to draw the line with sex in your home until he actually marries this girl. That is how I feel about this, and I realize not everyone would agree with me.

Jewel52 · 21/06/2025 23:37

SapphireSeptember · 21/06/2025 20:52

Oh come off it, my mum had four kids by the time she was 24, my sister had my niece when she was 20. 24 is an adult.

Are you suggesting it’s a good thing to have 4 kids at 24?

And how does being an adult equal being ready to parent? What a thoughtless response, like your DS was suggesting getting a puppy. Children deserve to be born to people who want them, not somebody who wants a shag but just forgot the contraception

Holluschickie · 21/06/2025 18:13

I will get flayed, but I have young adults living with me in a new build and I don't allow partners. If they want those, they have to move out.

Whoop, whoop, I applaud you. As you say, you aren’t going to win approval from everyone but you are setting the rules in your home.

I allowed my eldest to have his partner stay and it was difficult because of the size of the house and the impact on his younger siblings. They completely overstepped and acted like it was an Airbnb. It taught me a lesson, and encourages them to move out when they’re financially independent

WonderingWanda · 21/06/2025 23:29

Admittedly my ds is 15 and not an adult yet so I don't know exactly how I would feel but I very strongly suspect at the moment he suggested getting her pregnant would be fins just so he can have sex I may well have shouted back...
" You'd better bloody not!"

Girlmum1995 · 21/06/2025 23:23

PluckyChancer · 21/06/2025 18:18

She’s 24 with a child??? I’d tell him to run. 😳

Why

AutumnCountdown · 21/06/2025 23:08

Seeing as you now know they're trying for a baby they need to get their own place.
Better its done now than struggling to arrange it late pregnancy.

OneHazelPanda · 21/06/2025 23:05

I’d be so mortified if my parents heard me having sex that my partner and I specifically do not have sex when we visit. Sleep in the same bed but v PG13!! Agree with others that a brief word is needed about the thinness of walls and how grim/weird that is to hear them at it…!

Idiot123 · 21/06/2025 22:58

Just remind him that the walls are thin and you can hear his conversations also, then just casually ask if he's moving out if they're planning a baby? Make it sound like your just curious rather than giving a lecture, that's what I'd prefer it would stop me lol I'd have cried inside if I ever knew my dad could have heard me.
