Kissing comes naturally, but some ppl kiss mirrors and other things, i think its strange.. but only if i saw someone do it lol. I saw in a magizine that its normal to kiss mirrors/walls and stuff... So if you want to make it so hes surprized, make hte first move, and if you rly want lol you can practice!! And dont let your younger sister, and all your friends make you feel like you have to... Just make sure you don thave bad breath
lol!
