DSS Brought random girl home

[HappyMothersDayLadiesofMN]

DSS 17 is away college
Come home for the weekend as usual and went out drinking. At 2.30 made an almighty racket coming in drunk which woke us up
After 15 minutes we could hear him having sex. He'd brought a girl home.
After 30 minutes of this they came out of the room to the bathroom next to my bedroom giggling. By now I was bloody annoyed so I jumped out of bed and went out of the room. He's in his boxers she's naked going into the bathroom.
I told him to keep it down and that they were taking the piss. He apologised and said they were going to bed. I said I've heard you "being in bed" for the last half an hour.
We have no idea who this girl is. AIBU to be cheesed off. I found it massively disrespectful, not only did they wake us up which happens a lot when he goes out but to bring a strange girl home and have noisy sex then walk around undressed outside our room. What if DH had gone to speak to them. My DD was in bed in the room next to them too.

Is this acceptable for teenage boys?

Yes it is disrespectful. Get your husband to have a word. The drinking is normal but bringing randoms home is not.

Ffs 🤦‍♀️

I wish posters wouldn’t snipe at one another. One Sunday morning my husband went upstairs to our twenty-two-year-old son’s bedroom with a sausage sandwich and when he said,” Here son, get this down your neck.” A girl’s head popped out of the duvet as well. He went downstairs and made another sandwich. Good outcome, son married the girl & happy ever after. But they weren’t taking advantage in the same way as in the poster’s account. I believe teenagers live & learn, they are just being immature & selfish.
