People define "sex" in different ways. Some people believe that it only counts as sex if a penis goes into a vagina, but this isn't true for everybody. There are lots of different ideas about what sex can be:

• Vaginal sex (penis-in-vagina intercourse)
• Oral sex (mouth-to-genital contact)
• Anal sex (penis-in-anus intercourse)
• Dry humping or genital rubbing
• Fingering or hand jobs (hand-to-genital contact)
• Masturbation

However you define it, being sexual with another person takes a lot of responsibility. Before you have sex, think about what things you feel comfortable doing, and if there are consequences to them (like sexually transmitted diseases or pregnancy). It's just as important to think about what you DON'T feel comfortable doing. And if you're in the middle of doing something that you thought you wanted to do, but change your mind, that's OK, too. You can stop any time you want to.

If you're going to have vaginal, oral, or anal sex, talk with your partner about how you'll protect yourselves against sexually transmitted diseases.

It is also important to use birth control if you don't want to get pregnant.
