Ugh, bringing up porn to a guy is like shaking a bottle of catnip in front of your cat. Guys might just not be into the same kind of porn is all, and what you may like might bore them.
I watched porn with a girlfriend before and found it exhilarating, especially to find out what exactly her kink was. It was cool. I liked it so much because i was getting inside her head, so i understood her to a greater degree which was even more of a turn on.
PS: Midwestern here, but I live near college towns, so it's very liberal. One of my friends has a swinger relationship. I don't understand that.
