For the record, I have absolutely no problem with confused/curious guys posting threads in search of other people in similar situations (in the hope that they will start to feel more comfortable with their new found sexuality having met other guys in similar stages of life and established bi/gay guys) - this site is a great place for those guys to make their first step into bisexuality/homosexuality...just don't call yourself "completely/100%/... straight" when you do it.
