What Is Sex

For some people it’s only penis-in-vagina intercourse. For some people, it’s only penis-in-anus intercourse (anal sex). For some people, it’s genital rubbing without intercourse. For some people, it includes oral / genital contact. For some, it includes masturbation. The possibilities are many. For most experts (like Merriam-Webster and us), it includes all of the above.

People define “sex” in different ways. The Merriam-Webster dictionary defines it as “sexually motivated behavior.” This sounds right to us. But not everyone agrees with the dictionary or with us. People all have their own definitions of what is sex and having sex means.

However you define it, being sexual with another person — whether that means kissing, touching, or intercourse — involves a lot of responsibility.  It’s very important to protect yourself against pregnancy and sexually transmitted infections. And you need to make decisions about protection before you engage in vaginal, anal, or oral sex.
