no reason not to.
If you like him -NO. If you are not too sure if you like him- if ya wanna, then do it. If you dont feel right- no way!

If she's cute... YES!!!
Yes, why the hell not? If were both attracted to each other, why wait?
I agree with what my math teacher used say, you should always wait until the third date.
