Enjoy responsibly.

Sex. Sometimes it feels like everybody's doing it. Maybe you are. Maybe you're thinking about it. Maybe it's years away. Whatever.

You need to be ready -- in your head, and down there. You have to know the right stuff in order to do it.

Got questions? Who doesn't. "The Sex Lady" will break it down for you.

• Does size matter?

• How do you prevent STDs?

• What birth control options are there?

• If someone says they're a virgin, what does that mean?

• Am I ready? Am I normal?

The more you know, the easier it is to make safe -- and smart -- decisions about sex.
