This is kind of off topic since I'm a woman in a sorority but, the president of my sorority is a lesbian and is actually dating another one of my sisters. (they were going out before joining). Yes, it was awkward when I first heard about it but they are not that obvious. I just recently had to tell 2 of my sisters that pledged with me. Just because somebody is gay or lesbian does not meant that they are going to make moves after you.
