I feel bad for not watching porn

I know I only feel sexual drive when I'm with my boyfriend. He encourages me to watch porn when I'm in the mood and I'm not. His sex life involves him watching porn here and there.(mainly stuff I've said I'm uncomfortable exploring with him like threesome's and group sex). I feel uncomfortable watching porn because I have him to put all my sexual energy to. When I was single I'd watch it but now that I have him I don't. I don't feel a drive to watch porn anymore. I mean, I do follow pornographic Tumblr accounts yeah but I don't go to pornhub looking for stuff. Is there something wrong with me or my sex drive? I don't know. I just feel like something's wrong with me that I don't feel the need to watch porn?
