I've always been honest about my porn likes. While it surely has driven off some, it's actually given me a kind of intimacy with girls who are/were curious about porn.
I had a black fuckbuddy in the 90s and she used to bring over tapes she recently bought. All of them were of black girls and white guys. She especially liked being humilated by white men.
I had this very curious but outwardly prudish friend in college. We had a complicated sexual relationship since I was in line to be best man at her wedding.
I took her to the one and only porn theatre in the area where she saw her first porn films. She was anal-phobic and kept thinking that anal sex was happening when it was not. She lasted a good 15-20 minutes during the main feature, but started to cry and then bolted when the lesbian sex began.
But, it did loosen her up a bit.
She had a very slutty best friend and once when they were both drunk they let me finger both at the same time. She even sucked off my finger from her friend [getting her to do anything lesbian was a HUGE fantasy of mine].
In the end, I fell DEEPLY in love with her, she went back to her fiance, and I was left a broken shell.
