I was in the same position but I was 19/20, he wasnt allowed in my room at all or stay on couch and I wasn't allowed to stay at his house either (or anyone's house for that matter). He would stay over whenever my parents were away over night and I kept not coming home in the night at his house (that was 3blocks away). That started at 7months in and then 5months later I moved in with him. We have been together for almost 4 years, got engaged and now have a bub on the way.
I can see how she would want to sleep with him, I hated going home in the night. With an ex I used to see him after work in the night then a few house later go home and it sort of felt like a booty call in a way cuz I couldn't sleep over. It doesn't feel right. But then again I couldn't stay at his either.
And with my kids, they would have to be a long term partner. They can stay at their partners after 18. Partner can stay over after 17yrs as been together for 6 months but have door open. Its still wrong to have sex while parents in house I think..
Expecting our first on the 14th of August..
