My boyfriend bites my nipples hard
everytime we mess around/sex my boyfriend sucks on my nipples and he bites them as if hes going to bite them off sometimes they bleed just a little,and if i push his head away he doesnt let go he bites harder,,i liked it at first once in awhile if it wasnt too hard but just a little hard,but now he bites and doesnt let go eve n if i tell him it hurts.does he feel control over me?what is it,.so y does he do this and is it normal ??
