[M] I constantly jack off to pornstars that look A LOT like my fiancée’s bff

Feel guilty, but there are 3-4 pornstars that have a lot of similarities to my fiancées friend, and at the right angle look very much like her. They also happen to be the pornstars I masturbate to the most. I love my fiancée more than anything and am EXTREMELY attracted to her and we have a great sex. I’m also great friends with her friends boyfriend, so I feel extra guilty about my choice of porn. Should I?
