How come every time my boyfriend and I have sex, we fight either the day after or the day after that. If we just hang out we're happy as hell all week. But after sex it's like we always get in a fight. Not usually about the sex but like just anything. Like it could be jealousy issues or just anything that comes to mind. Even how we talk starts a fight sometimes like if we say "oh" ........ How do I fix this. I don't want to fight after sex every time.
