The young generation is a lot more flexible than boomers when it comes to playing with partners of both genders and taking pleasure from different and varying scenarios.
Yeah, thing is lot's of guys experience great physical, anatomical pleasure from anal apart from any psychological aspect derived from role as bottom. 10 or so yrs ago Sean Cody had a guy, can't remember his name, who ID'd as straight and LOVED to bottom. He would not kiss or give head however and when asked why in interview portion of a scene he replied: "No sensation." Dick in his ass felt good, in his mouth it didn't, so, he was only interested in the physical sensation and none of the emotional/psych aspects of sex typically experienced by many/most homo/bisexual guys. Now if he was in complete full disclosure honesty, ?, but interesting aspect to consider.
