The flowers are blooming, the bees are buzzing, and the layers are coming off. This could mean only one thing at Big Think: it's time to consider sex and the brain.

This week, we'll take you on a high-minded tour of sex for smart people. Our angles on getting it on will be unexpected and out-of-the box.

We'll reconsider prostitution; the changing nature of commitment, monogamy and addiction; the facebookification of flirting; Craigslist as the new Sodom and Gomorrah; and how we can all have a wild sex life well into our 80s.

Impossible for the intelligent class, you say? Well, you haven't heard from sex therapist Michael Perelman, founder of Mondoweiss Philip Weiss and authors Elizabeth Gilbert, Rachel Resnick, and Mary Roach—all sexperts in their own right.

Hold on to your bedposts and get ready for your neurons to fire.
