I would have never guessed this would be my very first post to the FO Board. IMHO, I believe that what you do with your wife/gf is your biz. And you can see what kind of opinions there are out here. This is how I look at it. An ass is an ass. Be it on a man or woman, it is an ass. Some dude says he's not gay, but would fuck a woman's ass. If you close your eyes, there's no difference! Well, except that a guy probably has hair on his. However, let's turn this around. It's not like she asked you to suck some guys dick while she watched. Even then, you're only talking possible Bi-sexual. What happens if a guy asks his wife/gf to lick some pussy? Would you be willing to suck a dick in order for her to lick some pussy? Chill out people! Remember, different strokes for different folks. Do what you're comfortable doing, and by all means, ENJOY IT! Just my .02
