Should we have sex ?

If your a Virgin and you never actually meet than nooooooo. You don't really know this guy 100% you can't really tell much about the person and the truth the person tells you without seeing his body language. Plus having sex at the beginning of a relationship will have you looking forward to nothing down the road. you don't want to base your relationship off sex. I don't see a problem with oral sex though.

Girls are filled with emotions, and if things don't work out, you don't want to get to attached to him, becasue he was your first time. cause you will.

Oral sex is just as good trust me, and if you guys really do like each other like you say you do, then neither of you should have a problem with waiting a little bit. give it at least 5 weeks of face to face dating.

wait to have sex.have him want it more.don't just jump into it

As hard as it is I think you should hang out with him in the real world for a while before you do the deed. Who knows, he might have a pimple for a dick and a really crap personality.
Better wait than sorry.
