Porn & Masturbation

Ok so my boyfriend watches porn a LOT and it makes me get this like pit in my stomach. It causes lots of anxiety and makes me think Im not enough even though I watch porn a lot as well and probably masturbate twice as much as he does. Someone please give me some advice on how to get over myself because him watching porn and rubbing one out doesn't bother me at all but its like I just get super bad anxiety. Any advice?
