your 1st newbie question.

I get it that you want to learn the process, not rush to a conclusion (let alone try to squeeze multiple shots on goal into a single meeting.)  

GFE...  is a general term...  often abused for advertizing purposes.  To ME (and not all agree) there are no set of rules as to what is included but rather a general feeling as I exit that this is what I'd like my real GF to be.  

I do not think you should restrict yourself nor tell her (after you meet, since it's verboten to discuss in advance) that you only want a make out session.  I think you should tell your chosen date, that this is "your first time", or you've "never had a GF"...  and you don't want to rush...  Let nature take it's course.  I'd suggest a meeting of at least an hour, maybe 1.5.  

I'd also suggest you go with a sexy but mature provider (late 20's to 30s +/-) willing to spend the time with you.  

Good Luck
skb
