Hah! Yeah, the PM who said this to me was a woman. This was friday night after we went out drinking/karaoke with a bunch of coworkers; we took a cab home together since we live in the same neighborhood, and the conversation kinda alternated between speculating on my dick, people having emotional breakdowns at work, and how she has a bunch of gay friends but they won't marry her. 
And while she's cute, basically I feel like I want to die. But like, I'm vomiting while I'm dying.
i really don't see how this is a bad thing.
Well, it's more like I feel pressure coming (lol) from a bunch of different fronts, while I really just want work to be work, and sex/relationships to be completely separate. So ultimately I rejected her because we work too closely together (and she's giving me about 100 9/11-level warning signs--signs that frankly I'd just ignore if I thought I'd never see her again), and of course that's already fractured how we're going to relate in the workplace, even on an explicitly professional level. And then there's the issue of my friend--the other PM--who apparently
also has a thing for me, which I guess I can basically ignore (since he should have no realistic impression that I'll switch sexual orientation any time soon) but it's almost the same situation.
