So I'm having sex with this guy and we're not in a relationship, it's just more friends with benefits but the first time we fucked, I didn't know that he doesn't use condoms and right before he put it in I realized he wasn't wearing a condom and when I asked him about it he said he doesn't use condoms and at the moment I just wanted sex so I didn't really care but since I'm not on birth control I was kind of worried afterward but I'm not pregnant however I feel that me and him should use a condom considering neither one of us is in any place to have a child and we aren't even dating but I don't know how to confront him and really make him realize why we should use a condom, how should I approach this?
