Amanda over at Pandagon recommends this site
to all teens and post-teens who need to know things about sex and having sex and birth control and just anything like that, and boy, is she right. Boy, do I wish I had had access to a site like this before I started doing the sex thing. And yes, yow, she's right, it's got stuff to teach me even now.
Send it out to everyone you know. Teens or not. That's my advice.
