A lot of questions about how to have intercourse, how to masturbate, and worries about what's all going on down there can be solved by simply getting to know your own body. In fact, I'd gander to say that before you let anyone else get to know it, you'd best know it yourself as well as you know your own face. Just like you wouldn't go out rollerblading until you knew where the brakes were, how to fix the bearings on your wheels, or how to find your way home from the park where you blade, the same holds true with your sexual anatomy.
