Take a quick second to make sure you don't have smudgy mascara or uneven foundation. If you're wearing cosmetics, you can touch up your makeup.If you're on a date before you think you'll make out, try to avoid eating any overly-pungent foods. While you're at it, fight off chapped lips with lip balm or chap stick. If you don't have anything on-hand, swish some water around your mouth and spit it out. Cover your bases by chewing gum or breath mints right before making out - if you can be subtle about it. (Don't go overboard, since strong scents are almost unbearable at close quarters.)

If you know that someone you like will be coming over solo later and that there's a good chance you'll be making out later, then you can make sure your room is neat and tidy, that there's no chance a parent, sibling, or roommate will interrupt, and that everything smells nice and is conducive to making out. If you're alone in a bedroom or a basement, you can dim the lights a bit without being too obvious about it.
Save the full darkness for later sessions when you know each other better. For a first-timer, though, it'll actually make things a lot more difficult - you can't see where you're going, and you'll want to be able to gauge your partner's reaction. You might think that total darkness will ease your nerves and hide any slip-ups.
