My first french kiss was not what I had expected.
My ex and I (we were both first timers in relationships) planned to
have our first kiss that day. So I suggested a park so that there
will be no people.
Well, to cut the long story short, I stuck my mouth to hers, and
hit her specs. I wear specs too. So you can hear the click sound
specs hitting together. Never mind, we removed it. And I tried
again.
This time round, when our lips met, I pushed my tongue into her
mouth, and guess what? Her teeth were closed!!! 
Can you imagine teeth grinding teeth?!?! 
Ok lah, after that, we got much better. But then, first times are
always awkward and amusing if both don't know how to do it.
The worse was our first sexual intercourse... But then, that's
another story...
