Zac Efron's kissing tips

"Be respectful of the other person and don't just get on in there and grope all over the place," Zac Efron tells J-14 magazine. "My favorite kisses happen when I've taken it nice and slow."

"When girls rotate their tongues around your mouth like a washing machine, that's not a good idea... I've never experienced a washing-machine kiss, but I've heard about them." source

Zac saves his biggest bit of advice for the kisser, not the kissee: "Go easy and take your time. Don't try to swallow the person you're kissing by opening your mouth so wide!"
