My bf(26m) and I(25f) have been together for 4 years. He is the only person I have had sex with. He is big and since we have been having constant sex for about 3.5 years, my vagina is a bit stretched out and it has become loose as compared to before. For about 2 years now, I've been wearing menstrual cups and I don't know if that is also a reason for this. Recently, we were talking and he jokingly said I should stop wearing the cup, because it's making me loose down there. I told him that it's not the cup, it's him. He laughed it off and when I told him it hurt me and that it's insulting. He apologised many times, said its a joke and that he's sorry that it hurt me. I feel extremely conscious now, I feel unattractive and I don't know what to do.
