Wet...but not even thinking about anything sexual?

[Anononononononnymous]

It's so weird. I'm a 17 year old girl and yesterday this guy told me over the internet that he has a little crush on me. Maybe it's because this is the first time I've ever been told that, but when he said that and when I've thought about it since then, I just get...wet. But I wouldn't say I'm turned on. I don't want to have sex and I haven't been thinking or fantasizing about sex at all and I don't understand why this is happening, especially since he said that over the INTERNET. I mean it happens so easily. It's crazy. Can someone explain this??

Please keep your answers kind and clean, as appropriate and mature as possible. Thank you!
