My son is 17 his GF 16. They've been together almost a year though the pandemic did restrict them from seeing each other for a while. They are both sensible but young for their age. I'm not aware of there being a ongoing sexual relationship. Is it really any of my business? He's our first born so this situation is new to us.
Today my son asked if his GF can stay over on Friday night. Im sure he means in with him and not the guest room! I'm not entirely comfortable about it. We have another child (11). I'm trying to be rational etc but can't really explain why I'm not ready for that to happen in my home yet. I need some advice and opinions. AIBU?
