What is the evolutionary purpose of a woman's orgasm? On today's show, Susie ponders this question and looks at a wired.com article that called the female O a "mystery". If an orgasm isn't necessary to procreate, why does it exist biologically? Men need an orgasm to produce semen, so the science makes sense, but what about women? Is the fairer sex entitled to pleasure just for a bonus, for fun and feeling good? So many questions… but here comes Susie to the rescue.

Next, a transsexual porn star tells all about what you won't see in an X-rated movie. Susie has been following the blog of PrettyQueer.com. She reads from the blogger's recent article about the top five moments never seen on a porn screen. It's all about the money!

Then in our "Try This at Home" mailbag, a listener writes in with a disturbing question. She asks: "I'm a high-school teacher and my boss wants me to include abstinence-only in our curriculum called Life Management Skills. How can I make this course more sex-positive and still keep my job?"
