How can I start a relationship with this pisces girl?

about 4 mouths ago, I met Megan, when I was landscaping a persons front yard, and she lived next door with her parents. She is 25, as am I. I started talking to her because she is super hot and I am a Gemini, so I am good at braking the ice. Anyway we hit it off, and we ended up going out to the bar later that day. We ran into a friend of mine, and we were all having a good time. Later on, My friend and I both ended up screwing megan in my car, than again later back at my place. And later that week end, she came over when I had some people over, and she ended up blowing 6 of us. Like I have never met anyone like megan, she is just totally shameless about things, and We have been friends with benefits for awhile, but lately we have been spending alot more time together... And I would like to be in a relationship with her. She is a double Pisces, and I am a Gemini with a Leo moon. It doesn't bother me that my friends and I have all banged her, I like her, I like someone thta doesn't judge other, and is happy with them selves...
