Tips for first kiss!?!!?

Okay, so I'm almost 13, and I know you're gonna say "You're way too young", but actually, my question is not asking whether I'm too young or not, is it?(: Hmm? Nahh...So, I'm moving, and this guy I've like for 3 freaking years (we've gone out a couple times) wants to kiss before I leavee. So, um, it's his first kiss and mine, too. On the first kiss people don't usually use there tongue, right?! Cuz that seems kinda much.. And like what if I'm a bad kisser!?!?!?! Hellp, and i need some tips.....xoxoxox
