First kiss did anyone else turn ninja?

Ok so I had my first "proper" kiss not long ago and i have to say it was one of the most awkward embarrassing experiences of my life. Im 16 which is kind of old maybe and im kind of immature and when he tried to kiss me i was expecting it and wasn't at the same time so i ended up head butting him because i went to panic mode:S anyone else got any grimacing first kiss stories to make me feel better?
