No rude comments I just need to vent my boyfriend is addicted to porn and I’m hurt

I don’t want any bashing I just need advice and support it’s going to be a little long but I just need help 😔 Our relationship is great I’ve been with him for 4 years and we have a beautiful baby girl on the way. I’ve always known he’s struggled with this porn addiction since he was 9 years old and ever since then he’s became more addicted even before he met me. Its been bothering me. I’m not the type who’s going to leave because he’s addicted it’s not his fault im just the type of female who’s very insecure about myself like my body sometimes my looks etc. Hes already explained to me it’s just entertainment and I don’t really know how the male brain works because I look at it differently but he told me none of those naked pornstars he sees means nothing to them he just says it’s an addiction and it’s just entertainment he’s trying to stop and if he sees people having sex he’s going to get horny. But with my stupid insecure self I’m over here thinking he doesn’t find me attractive I don’t have the body they have he likes anal but I don’t give it to him so he respects that so I guess he watches videos about it I’m over thinking he wants something different or he is just tired of me but our sex life is fine so I don’t understand what my problem is. He never talks to me about it because he feels like he’s hurting me and he doesn’t want too see me upset he tells me he loves me and our daughter and he doesn’t want me to think I’m just unattractive because he told me those porn stars don’t mean shit to him he tells me he’s in love with me every single day and I see it but it’s like when he watches porn I just feel like a piece of shit how can I understand I can’t stop feeling like this 💔😔
