Sex research...sex advice. The names that stand out in this field are the Kinsey Institute. In fact, the 1948 Kinsey Report has become such a part of our pop culture that it has a blues band named after it. Other sexperts include Dr. Ruth, Dr. Drew, and William F. Fitzgerald, Ph.D. aka the Sex Doc. And who could forget Dan Savage?

Actually, a little more looking would reveal that nowadays, almost everyone wants sex advice and almost everyone else want to give it. (Looked at the magazine rack of your average checkout counter lately?)

So much for just "doin' what comes naturally".
