I'm on this dating site and am talking to this first guy, when this second guy sends me a message. I answer it because his picture is pretty good looking. We start talking about normal things, but he's kind of quiet and reserved. Then I say, "What about me would you like to know?" and suddenly I'm answering his questions about sexual things. Positions, sizes, and whatnot. Well, it gets a bit odd here, as I very much realize I talked to this guy before about the same things, but he stopped responding to me for some reason. Is this normal for a dating site?

Just curious.
