I had a few gay friends, male and female, at University, but we kinda lost contact, and now I speak to them online once a year if that.
I tried to be friends with a guy I was dating afterward, but he kept wanting sex and I wasn't into it, so that stopped too.
I'm happy with the straight friends I have - our personalities and likes match, and that's all I'm looking for in friends. Sexual orientation doesn't bother me.
