Have I fucked up here?

So, I had a first date last night with a very nice girl, really hit it off, share a lot of interests, blah blah blah. We've already agreed to catch up for a second date, so things must have gone pretty OK. BUT! I walk her back to her apartment, we stand outside talking for a few minutes as she finds her keys, I give her a hug, all is good.

The question is, was that the perfect time for a first kiss, and if it was, how far have I climbed up the lame scale? I mean, do people (OK, girls) expect a kiss on the first date? And if they do, what do they think if they don't get one?

*sigh* Damn I wish I wasn't so crap at times...
