My girlfriend told me she was bisexual, which didn't bother me in the slightest bit. How could I be jealous of a woman being with my girlfriend? As long as everything is being discussed freely with each person involved, it's not a problem. If she were to go with a woman behind my back, then that would cause many trust issues.
As long as there is trust, then there is nothing to worry about. I don't mind having my woman checked out by other guys, as long as they don't get out of control. I want her to feel like she is the sexiest woman in the room. If they are checking her out, I know I've got what they wished they had.
If it pleasured her, then yes. But I wouldn't want it so often that it turned her away from me. But, as a fantasy for her, I would do it.
Of course they do, but not as much as taking your lady to a strip club and seeing her get turned on by it as well. Not all guys have it that lucky, but I do.
Being able to make a woman moan and have an orgasm (or 2 or more) is the best way to show how good you are in bed. For me, it's all about pleasing my woman.
