SO won't stop with porn

Am i wrong for asking him to stop watching porn ? It didn't used to bug me but I recently has been since we made a sex tape . I don't know I just feel like I am not good enough and he's a great guy and I know I have nothing to fear in the cheating area but when I asked he got all mad and kept pulling the guy card saying they are programmed differently blah blah. And I just don't get it I am a girl who has needs and usually wants it way more then he does and I don't need porn. What's wrong with me ... maybe it's just all in my head and over thinking
