What delightful tale of sexual deviance does surprisingly kinky advice columnist Dear Prudence have for us today? A woman contemplating dating a stranger she caught sniffing her crotch sweat at the gym? Yes, I think that will do.

I'm a fit, attractive 30-something single woman who enjoys working out at my local gym. A few weeks ago I noticed a cute guy seemed to have a similar schedule as mine. We also seemed to have a similar workout routine-bike, weights, swim etc. I've tried smiling at him once or twice, to see if there was any interest, but neither of us has made the first move. Then yesterday, I returned to my stationary bike as I had forgotten to wipe it down, and I noticed that he was standing next to it, rubbing the damp seat with an odd look on his face. He then pretended to have dropped something, but I saw that he was actually sniffing the seat, before returning to the locker room. I don't think he realized that he had been spotted. How do I proceed? He is very attractive, and I guess he is into me as well. Do I say something about what I saw, or should I continue flirting with him knowing what I know?

Dear Prudence's answer: "He's now made the first move. Don't you make the second."

Dear Gawker's answer: Never close your mind to the erotic possibility of Shaggy Dog cosplay.

(Oh Heavenly Dog, too.)
