ah.. the first kiss.
i just recently had mine, and to tell you the honest to god truth, it wasn't all that great.
it happened in the hallway at school right outside of a bathroom.
he started out like he was gonna hug me and he came close and tilted his head. i did the same and we...kissed.

it was kinda wet and slime, truthfully.
the first kiss is usually a peck, not a full-blown make-out extravaganza. all a peck is is when your lips just touch. no tongue action is involved. it's not that hard... if you want to practice on your hand or a piece of fruit.
good luck!!!
