My boyfriend and I want to have a threesome with another guy. I never want to do one with another girl because I just can’t imagine him being with another girl but I understand if that comes across as unfair. FMM has been a fantasy of both of ours and I told him if he’s even the slightest bit unconfortAble with it then it’s not happening because I don’t to jeopardize our relationship. I need opinions. Is this a crazy idea? Is it going to be weird between us afterwards? Is sex going to be boring or unsatisfying if we just went back to what we normally do?? I want to have this new experience but I don’t want to harm my relationship with my boyfriend in any way. If anyone has been in this situation or just has some insight I’d really appreciate because there are so many ‘if’s and I want to make sure I’m not about to make a mistake.
