That's a personal call.

If you can do it without getting attached, and think the other person can too then I don't see any problems with it. I've had a few girls I've messed around with on occasion and not had any problems with them. Then again I never asked any of them to 'be my girl'.

If you don't know...shit, I say try it anyways. Worst case scenario you get too interested and get your heart broken, either that or it goes visa-versa and you end up with a stalker
