I fear that im a pervert (NSFW WARNING)

I have this problem where I accidentally look at peoples private parts. It happens with EVERYONE, even my dog. But I have so many problems which im gonna discuss further.

I think that sometimes i PURPOSELY looked at private parts. I remember this one time recently I saw fanart of a lesbian ship and then I tried not to look anywhere out of fear that id look at the private parts of one of them and then I suddenly let myself look down at the complete bottom, thank God these werent private parts but iirc i thought that they were there and im scared that it implies that id let myself do that!!!! Also recently I saw a picture of a girl on a subreddit and i also tried not to look at them, and then suddenly the same thing that happened earlier happened. It feels like i let myself look.

I also remember once while obsessing over this two months ago,I checked if my grandpas private part is noticeable for some reason!!! I dont think it was directly because of this though.

I would also add on something else that i did but i dont want this to be so much. I already stopped obsessing over these things at once and I immediately regretted ALL OF THEM after they happened but I need to get this off my chest. This is killing me. Though im sorry if this is too inappropriate. Im scared that i may be a pervert, and im scared that I shouldn't let myself live casually if i dont know if im a good person and this is one of the reasons why.
