take it slow. dont let him do anything you dont want. you'll get better as you go. its only keeessingg
I should also mention that I don't feel comfortable talking to my friends about this matter because they are friends with him as well and are sometime err.. not very discreet.
I wouldnt tell your friends. Just hang out with him if you like him. Tell him youre a horrible kisser, and he'll let you practice (trust me it works )
