How do you snog?

Don't take things too far too fast. Nothing is more uncomfortable than going faster/farther than the other person wants to go. Start out with gentle kisses. Gradually progress to longer kisses. Some girls like it when you run your fingers through their hair. Some guys do, also. Sometimes sucking on their bottom lip makes them happy, sometimes sucking gently on their tongue. It all depends on the person. If you find it fun to swirl your tongue around the other person's, go ahead. When kissing, it is really hard to mess it up without trying. Just go with the flow. And try to look for cues from the other person. Just have fun! =)
