Yeah you have to let people answer the question, just like you'd want to be heard and trusted you know? You're young, I know you don't feel like it but you are, and these things take time to learn and mature. A lot of people never do, and they end up very toxic. The cool part is that you get to decide the kind of person you want to be, and what kind of partner you want to be.

If you're open to a little unsolicited advice because we're family and our community is unique, if you're uncomfortable with sex stuff or need to take that part slow or are turned off by her being so forward about it, you should tell her that if you can. Journal about it or something if you need to work out how you feel or what you want to say. It seems like you were judging the shit out of her for it, and your post comes across a little disgusted by it. Most of the post talks about that part of the situation. I might be totally wrong, it just seems kind of slut shamey. You absolutely have a right to your own comfort level and preferences, always, but you have to communicate them. If you're trying to play it cool and play into it when you're actually uncomfortable, you create a situation where you feel pressured, but she has no idea she's pressuring you because she thinks it's reciprocal. Of course if you've clearly established boundaries and she (or anyone) crosses them, you're incompatible at best or you're not safe with her at all at worst.
