At my undergrad school, I do beleive that our National Championship softball team had 3/4 lesbians on the team. So pointless.. Few bi's, but always made for a good party favor when they would make out in our fraternity..
I've had a few gay friends. They were great to talk to because I'd ask about their lifestyle and why they chose that way. We'd get into the whole nature vs nurture argument for hours and hours.
I can still remember one who told me about his date and how I happy I was for him for finding someone that he could love. The people I was with at the time were grossed out by the thought but not me because I knew how much he cared for the other person.
