So I met this girl via a cousin of mine. She seemed pretty into me, and was touchy feely from the start. After about a week of some light flirting, touching and what not, we finally seal the deal. She seemed really into it, and I made her cum multiple times. Fast forward to today, I see her again and we have some alone time. She's all over me, we're play fighting, she's grabbing my dick and the whole nine, I of course go in for the kill and get instantly rejected. Thinking I may have been too fast, played it cool and let up. So as the night goes on, she still is staring at my lips, making comments about how sexy I'm talking, and keeps Grabbing my fucking dick! I get a little excited and just pull her into me, and once again try to initate. She's not having it, this then leads to her trying to scold me like I'm some kind of kid. I mean she raises her voice and even slaps me across the face. This was my final straw, I tell her to get her shit and leave, I won't tolerate this wishy washy bullshit.

My question is: What the hell was I doing wrong? I mean I was getting all the right signals, and the last time we fucked she was really into it, that, combined with her actions before me putting her out have me really confused.

For context this girl is 19, just turned two days ago. I don't know if that means anything, but I would really like to know, what type of behavior I may have exhibited that turned her off.
