Am I wrong for feeling uncomfortable? F25 m27

Okay I just want to know if I’m in the wrong or not , give it to me straight. I’ve never lusted or cheated on my Boyfriend before . for some reason when I get into a relationship I don’t find anyone else attractive or anything, my eyes are only for him even if I try I just can’t look. He had definitely looked at other woman constantly glancing, he has trouble with porn as well. He has mentioned wanting a pocket pus when I gave birth ( even after the teen light to have sex ) I just felt like I was never enough for him , but anyways I’m getting off track. Today I asked him a hypothetical question, if a woman randomly starts touching you would you get hard , he told me yes. I felt sad because if it were me I would feel violated and I wouldn’t get aroused. (He told me he wouldn’t put himself in that position tho he’s just sneering. The question . I’m also sad because i want to feel good about him when I’m not around , I want to feel like yeah no my man wouldn’t do that to me.

Am I wong for being uncomfortable that knowing confidently he would get aroused ?
