This may sound bad

I know it may sound bad or maybe even dumb but I know my SO just seems like he's only attracted to models and pornstars cuz that's all he would look up, especially on twitter. I feel like I'm not good enough for him at all and that maybe he has to think of someone else to even do anything 😔 This honestly really upsets me. I could understand just looking up porn but to search specific people just seems too much like they HAVE to be attractive. I'm at the point where I don't want to have sex with him anymore, honestly. I don't think it would hurt my feelings at all either. I'm just not sure what to think about it. It's always about stoner girls who are nude and he wanted to get this sticker for his PS3 controller of one on it. I should've just let it go and he could've just had it. I can't tell if I'm overreacting or if this would put any other woman down.
