Well, I am not attracted to boys, but if you don't mind, I will give my own perspective. As skewed as it may seem with me being attracted to girls. :p

1.) Oddly enough, though I am attracted to girls, and am married and have no problems having sex with an adult woman (though I do find small breasts much more alluring on a woman)... in the past I have also had adult same-gender sexual experiences. They were fun and erotic, but they left me empty. I could never bring myself to kiss another man.

2.) I wouldn't have any problems with going out with a woman. Ideally she would be younger than myself (18+ I should specify). However, since I am married it tends to put a damper on the dating scene. heh

3.) No, not really. I am uncomfortable around people I don't know very well, but that is pretty much it.
