I used to be one of those couples before I got divorced. And you are absolutely right. It is,about communication. If I didn't like him doing that, I would have told him. And vice versa. A lot of people on this site are young and inexperienced.
I think that's the issue. Once you are in a relationship that you give your house key to the person and there is constant sex like that it becomes a bit of a nice thing to be woken up like that bc there is trust and actual intimacy etc and after many years in a relationship sometimes people are tired, want sex, but don't want to do a lot of the work so this works great LOL
When the MC kept subjecting his neighbour to sexual harassment, nobody cared?
Also, a lot of couples wake each other up in "fun" ways. Until Ideun says or we see him feeling hurt because of the actions, I don't think you guys need to March.
