Mad i wanted sex ,instead i get turned down

I got my period days ago and I'm not the kind of person to have sex on my period cause I thinks its not good so I stayed over my boyfriends house to spend time together since he's a guys and he knows how I feel about sex during period I pleased him another way gave him a bj almost allday so then since its my fourth day on my period I checked to see is my period was at least light so I can try fucking him and turned out it was and it was super light so I cleaned myself up took a bath he was nearly asleep I grab his junk and I giggle and he all of a sudden turns on his stomach and puts a pillow between us my jaw dropped and I am now pissed and frustrated
