Relationship problem!!!

Does anybody else find it incredibly insulting when their SO watches porn & jerks off when you're in the room, sometimes even laying next to them???

My, now fiancé, won't have sex with me when I'm on my period. So I've compromised & told him its fine that he watches it, as long as I'm not around bc I find it insulting, as I personally have body image issues. He personally thinks that if I can use my vibrator around him that he should be able to watch porn around me. Does anybody else see these as 2 completely different things???
