It's not a whole lot different than straight sex - different positions at different times. Though there are "tops" and "bottoms", I think most are willing to give as well as to recieve.
And I won't bring up the fact that if you'd THINK about it, hehehe, you'd realize they can give each other blowjobs at the same time......
MY question to my gay friend several years ago (realize that I was brought up LONG before women paid for dates

), was who paid for dinner and the movie.
