She wants to lose her virginity?

I think this is simply an issue that you need to talk to her about. Often the first time can be kinda painful, regardless of how "gentle" the guy is. It takes a few times for it to feel great for the girl. So if she's aware of that, you shouldn't feel bad if she is sort of sore after you guys have sex. It's part of the process, so you need to accept the possibility that you might cause her a little bit of pain the first time. But it'll be worth it for both of you in the end ;].
Hope this helps! Good luck.

I think instead of the hinting, both of you need to kinda say straight out if she's ready for it etc cause you don't wanna do anything wrong, or for her to feel forced into it. don't worry :)

Tell her what you feel, that you don't want to do something wrong, that you don't want to hurt her. Ask her to really think it over and see if she'll be willing to take more time. Let her know that once you have sex, it's really hard not to and it's not something you can undo. Ask her if she would rather loose her virginity on her wedding night, then some random night that would have no meaning later in the years.

If she still persists, do what you think is right.
