tips

Im a virgin, but in the coming week or so I have an opportunity to lose it with a decently attractive girl. Problem is, she's not a virgin and although I haven't told her one way or the other, im confident she thinks I am not one as well. I would rather not tell her so that the opportunity isnt jeopardized or made weird, so I was wondering if anyone had some tips to pull it off. I don't need to be the best ever, but I'd love to be able to give her a pretty good time without revealing the fact its my first. Any tips would be greatly appreciated, thanks!
