My sex life has been shit for the past month or so. My boyfriend is moving in 13 days, states away, and we won't be able to have sex or be intimate at all really until he comes back home. But still, for the past month, sex has been of no interest to him. Any time he actually decides to have sex with me- 10 mins in he asks if we can stop or he tells me he's not going to come. I recently told him how I felt about this and that it hurts because I feel like it's mostly because of me that he can't finish. (He has no problem jerking off to porn daily full of girls he calls "his type" which look nothing like me) I've been horny af for forever and he tells me to just masturbate. I can't masturbate. I have a history of sexual abuse and I just still can't bring myself to do it without breaking down unable to continue. (He knows this) Then for tomorrow he finally agreed we could actually have sex. And today I got my period which-for him-means sex is out of the question. I'm left so upset and he just doesn't care. No clue what to do. Any advice??
