I've been with my boyfriend for a year and a half he is nice and sweet says he wants to have a baby and a family but when he want to have sex with me he seams to find him self putting his hands on me and hurting me .then expecting me to have sex with him .when I asked him why he feels the need to get abusive with me he says it turns him on wtf I don't get it I told him we can like make it work in bed that he don't have to hurt me that we can roll play but he said it's not the same that he.likes to see me cry that he gets turned on .idk
