I have been very good friends with this girl for a while, and it seemed like there was very little sexual tension between us before the past month or two. Things began to heat up between us, with both of us lamenting our relationship status and how we felt lonely and horny. As we became closer, we started realizing that we both really identified with each other and even made frequent jokes about how we are "exactly the same person", because our life situations and personalities are so similar and mesh so well with each other. This culminated about two weeks ago, when we both ended up admitting to each other than we wouldn't mind a purely sexual relationship between the two of us since we were both so horny.

Now I don't know where we stand. I don't know how I feel about her--I've never really even been in a real relationship in my life. I'm attracted to her, and I care about her a lot--but I'm not sure where the line is drawn from a FWB situation with a close friend to a relationship. I know she's also confused about her feelings about me, and we haven't even had full on sex with each other yet (although we certainly have been very frisky and had some enjoyable sexual encounters with each other). 

What makes a "relationship" exactly? What is the difference between friends having sex and a couple? I don't know how to define this and I'm really confused myself, so please ask for any additional information and I'll clarify in the comments.
