I've been hanging out with this girl for awhile, and I like her and she likes me a lot (no doubt on this). Yet I can't seem to cross the barrier into actually kissing her or doing much of anything. I want to touch her hair then kiss her or do SOMETHING. Everytime I'm about to I just stop in a paralysis of fear. I don't want to know what to do, but rather how to be confident in these situations. Don't say "don't think about it, just do it," as obviously that's my problem is that I haven't yet been able to just do it. I didn't used to have such a big problem with this, but for some reason I do now.

This is to the point where she still likes me a lot, but if I don't do something the next time we hang out, then it will almost certainly be too late. What can I do to snap myself out of the state of a paralyzed wuss? I'm even absolutely certain that she wants me to and I haven't, I guess my last relationship had a bigger effect on me than I thought, but geez such behavior is unacceptable! I need to snap out of it! Help!

Just so we're clear. I do NOT need to know WHAT to do, but HOW to get myself to the point where I actually do it.
