I can tell you that my lesbian friends start to gag if they see a males genitals. They want nothing to do with a man sexually. Yet when they watch a dirty movie, they like to see a well endowed man doing a little female. But maybe that's cause of what they do in the bedroom (can't say or I'll be deleted).

I do believe in the sliding scale, but I also think some are to the very far left or right on that scale. Most however fall somewhere between. I write for some,,,uh,,, erotic,, shall we say sites, and I sometimes have a damn hard time writing steamy stuff about things that really turn me off!
