ALRIGHTY! rAFC here! Quick help with a situation.

Ok, HB10 and I (she also happens to be 18...big part here) hung out, and finally kissed. Now, this has happened a couple times, and it is getting dangerously close to relationship territory. My problem here is escalation. We haven't discussed sex, and I think we should, because every time I brush past her chest or other zones, she immediately goes to intercept before I even get there. She is a smart one, who knows how to defend herself before something even happens, to not cause a problem (such as before we caught up...she told me it was just as friends... I told her that we would never work out, she's too much of a good girl...and now look what happened!)

My problem here is ... how do I escalate it???? Do I just keep going and let her get comfortable with each step? I kissed her on the neck and she really enjoyed it, but she said "that's enough for now." My guess is she just... hasn't been touched this way. EVER.
