In reply to Jessica.

Why, yes, in fact -- what you have described (pressuring someone into sex after they have repeatedly told you 'no') is, in fact, sexual harassment. I am a woman, and a feminist. And the behavior you have just confessed to is gross and rapey and awful, no matter the gender of the perpetrator and the target.

Regardless of whether it "worked" or not, it's pushy, creepy, coercive behavior. He might very well have just decided to go along with it because it was easier than getting you to stop HARASSING him. (Certainly I know plenty of women who have said 'yes' to sex because they gave up on being heard when they said 'no'.)

Decent adult human beings respect people's boundaries; they don't keep pushing when someone says 'stop'. Your desire to fuck some guy doesn't trump his right to have his boundaries respected.

Men are expected, in this culture, to be "always up for sex"; he would likely have been laughed at if he'd tried to report your behavior. I want to tell that poor guy, across miles and years, that what happened to him was not even slightly okay. If I'd been there watching, I'd've offered to help him report you to the conference organizers and/or the cops.
