So the big night has arrived... PROM NIGHT! You look amazing in your dress and you have the perfect date. Or maybe you just put on your crisp tuxedo jacket and you are ready to pick up that special girl.  Everything has fallen into place and you are about to have the time of your life.

Like many others, you are probably thinking about prom night expectations -- specifically "after-prom" expectations. Is prom night going to be special because you will always remember dancing the night away with your friends? Or is it going to be memorable because it is the night when you and your date finally have sex?

Prom is supposed to be a night of fun with your friends and you shouldn't feel pressured to do anything you don't want to. While most teens say they feel pressure to have sex, not everyone is doing it. In fact, about half of high schoolers haven't had sex. And remember, you can always say "no" -- even if you've said "yes" before. There are many good reasons to say "no" to sex -- protecting your feelings is just one of them.

If you don't want to have any post-prom regrets, the best advice is to not have sex at all. In fact, most teens (60%) who have had sex say they wish they'd waited longer. If you feel any doubt about being alone with your date after prom, make plans to stay with a group. You can't go wrong by enjoying a special evening with all of your closest friends.

If you are thinking about having sex, you need to make sure that you and your date are on the same page and that you have a plan for protection. To make sure this happens, it is important for you and your date to discuss your plans and expectations long before prom night arrives. Talking things over beforehand will help guarantee that you will not be caught up in the moment and do something you are both not ready for.

Sex is serious and has very serious consequences. Not having sex is the only foolproof way to prevent pregnancy or STDs. But if you do plan on having sex, you must use protection every single time. Now's the time of make your prom night plan.
