Voice your fears to her about it. Make sure it's a 'conversation' and not a chat.. Any talk less than 2 hours is not a full discussion of the problem(not that it's a problem)..
If you and her then both agree that it is something you want to try, then all i can say is GO FOR IT!! As it has been said: You only live once.
But like They and I said.. Make sure you weigh the pros and cons first..




And when your done.. can i have your friend??
