Re: Question (for the girls probably)
It really depends how close you are. The fact that you're a boy and she's a girl may make her uncomfortable and awkward.
Why do you feel the need to have this conversation? Is it for her sake or yours? If you have questions you have here and VT to get them answered. Seeing that she's 16 I'm sure she's old enough to find information so I don't see it necessary to have, but it's up to you.
