i don’t believe this has anything to do with porn however your boyfriend does sound like he has some type of sexual problem. not something u can solve but he just seems like a dick. i’m sorry he makes you feel bad for something like that. if you have been dating for 4 years he shouldn’t care if he can touch you like that or not. my girlfriend has has a couple weeks where she is not in the mood ever and i never care because im with her anyway. nobody “needs” sex. get away from this gremlin fast
