I am guilty as charged. Not right now, but several years ago when I used an online-dating site, and one single girl replied, I did kind of go slightly sexual innuendo-mode. Although I don't remember it very well right now, and it might have been just excited unintelligible gibbering.

Eh, I don't know why, but I'm interested in what the site that only allows women to initiate contact is. I suppose I'll just go look at it out of curiosity.
