I think that if you're really going to snog someone and it's going to be a perfect snog, it's got to be between two people that really like each other, rather than someone you think is fit and you snog for the sake of it. That normally turns out not to be a good snog. But if you have two people that really like each other, then fair enough. Really, it's a little mix of kissing, a bit of lips, maybe some biting, and then a bit of tongue and stuff. It depends on what kinky little minx you've gone for on the night.
