Nonexistent sex drive

A year ago I discovered my fiancé had porn saved in his gallery. I wasn’t snooping so don’t come at me - he opened his gallery right in front of me. I was hurt because he had told me earlier in our relationship that he didn’t watch porn anymore because he had me & I believed him because I had no reason not too. So when I saw it in his gallery, I thought he had picked the habit back up only after I got pregnant & that made me believe that he wasn’t attracted to me anymore. Low and behold, he had been watching porn our whole relationship, which in some ways was actually comforting.

But I wasn’t prepared for the other things I learned about his porn habits. He followed porn stars on Instagram, was in countless sexual Facebook groups, and what really disgusted me was the kind of porn he watched, or rather, the type of girls he was watching. He’s 40. But he clearly has a fetish for young girls. (And ik people are gonna say what 40 year old man wouldn’t be into a young girl - but judging by the dvd collection he has, he’s always been into girl significantly younger than him - he has a dvd of a girl who was 18 and he was 27 when he purchased it) His porn history and dvd collection are all exclusively amateur girls that are anywhere between 18-25 years old, and it’s not even JUST their age that kind of changed the way I look at him, but it’s their overall appearance that really has me feeling insecure. They’re all super slim and flat chested. One of them (Alaina Dawson) literally looks like she could pass at a 14 year old. Similarly, Lily Ford, Arya Fae, and Riley Reed seem to be his go-to’s.

I think what further gets under my skin about that, is that I’ve caught him numerous times checking out our young female coworkers and other young women just out in public. I never thought I’d envy girls that look like these amateurs “porn stars”. This shit has me so insecure that I dread going out with him because I’m constantly browsing around to see what girls are around us totally paranoid that he’s eyeball fucking the cashier fresh outta high school or some shit.

And the way this fetish had made me feel so low about myself and has made me kind of feel like my fiancé is slightly pedophilic (ik technically they’re legal....but if the legal age was 16, would he be into girls that young?), has really turned me off to sex with him. And for a while, I was getting away with it but today he questioned why we haven’t had sex in a while, and I beat around the bush to avoid telling him the truth because he won’t let me express how I feel about this - I’ve more than beat this dead horse in the face so he’s super over hearing about it. I don’t know how to remedy this situation. Help!
