Search Results: girlfriend is talking sexual things

So there's a girl who I have been talking to recently for the past month, and she doesn't make her intentions clear to me whatsoever.

She is always happy and excited to see me and her close friends are also giving me different ideas of her intentions. To give you an idea of what it's like, just last week she was sitting in my seat for class and I asked her why and she said, "Cause I wanna sit on your dick." We both make really sexual remarks about each other all the time and talk about how one day we're gonna get married and what chores we would do, stuff couples talk about. We always make strong eye contact and laugh together about the dumbest things. Also I recently took another girl to homecoming (it was girls ask guys) and the mixed signals girl confronted me about it in a joking manner, but it goes back to the whole couple-type conversation. Finally, my friend took a picture of her and sent it to me and the caption was what she said which I can confirm she said, "I want to see Jack's dick" and my name is Jack. Sounds like she's into me, right?

On the other hand, that same guy who sent me the picture of what she said told me she is interested in another guy (not sure how much). Also, my other good guy friend told me the mixed signals girl told him one of the sexual remarks I made about her while we were talking the other day, and there was no reason for her to tell anyone what I said. Imagine if I told the whole school she said she wanted to "sit on my dick." Also, it may just be a coincidence, but she has been busy the last two weekends I asked her if she wanted to hang out. But countering everything I just said, one of her girlfriends was texting me the other day about how she was with "my girl" (the mixed signals girl) and they sent a video where the mixed signals girl blew a kiss and winked.

I am pretty wrapped up in this girl and I think she's clogging my judgement. Can anyone infer if she's interested in me and/or what my next step should be?

Thank You.
