Although I've done it, and done it plenty of times, I've never actually wanted to have sex with someone I didn't feel an emotional connection to. For me, it's simply awkward, and even, yes, embarrassing.
I don't think being gay means being promiscuous. It's never meant that for me. I lurch from crushes to crushes, some of which cross the line into love. These are the people I want to be with.
My first gay experience was truly dreadful. A guy who followed me home and all but forced himself on me without any suggestion of using a condom.
For some reason, though, the way the gay world is structured, you pretty much have to be prepared to have sex with someone before you can get to know them. It's like, "We'll have sex first, and then we'll talk."
