<human>: 24M here, dating 25F for 3 months now. I've been in only one other relationship, back in college, and it was with a girl who was extremely sexual, and there was never much discussion of sex before it just happened (she said that she usually waits 3 months in a relationship...ended up waiting a week, and it was a regular thing after that until we broke up). 

In the last six months or so, I've gone on multiple dates with three women (the others being 20F and 24F), and I'm now dating one of them exclusively, as I said before. Sex did not happen with any of the other girls (although I wasn't ever "in a relationship" with either of them), and has not yet happened with the current girlfriend. The first time I tried to escalate things with her, I got shot down. I tried rubbing her breast while we were making out, and she gently removed my hand and held it instead, and I haven't really tried anything since then. I don't know anything about her sexual history, if she has any, and I'm not sure how to bring it up as a topic. I like this girl, I find her extremely attractive, and I'd like to sex her up at some point, but I'm not sure how to bring it up as a topic of conversation so that I know what she likes, what her boundaries are, or if she's waiting until marriage or what-have-you. My brain is telling me that she's just taking it slow because we didn't even kiss until our third date, but I've also had the thought that I may have found someone who is even less sexually experienced than I am and she might be in the same boat about the sex talk. I'd like to be able to bring it up in a non-awkward way (if that's possible), but I want her to know that her company is important to me, and that I'm not only thinking about sexy time. So, Reddit, can you give me some advice on this?

Can you condense the text into three sentences or less?
<bot>: Haven't had sex with her, would like to, don't know how to bring it up in a non-awkward manner.
