Is My BF GAY or does he just have issues?

Okay so my boyfriend is kinda weird. For when we "make love" he ask me to finger his butt hole and hit it rom the back (I have no penis) so i put on a strap on but anyways when i hit it from the back he starts yelling "Do it like a rapist! Ra Dat Dat! Rape the ***! Mannn!" So i get scared and I stop then he starts to cry. So i start again. He yells "Come On, Rape the Boot-Boot-Boot-Tee" Its kinda weird because I'm not getting any pleasure from it but i just want to make him happy. And everytime when I cook something for him he alwats ask me to cook him something like a rapist. I be so confused. Then he gets real mad and starts yelling "why cant you cook the way i want you too! Like a rapist!" I'm starting to feel uncomfortable around him but i just want him to be happy. He says he want to marry me aslong as I "hit it rom the back from now on" BUT I WANT TO HAVE KIDS I dont know what to do should i stay? or should i go?
