'Should I Date This Weirdo Who Sniffs My Crotch Sweat at the Gym?' Asks Very Single LadyS

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.)
