Fellatio Workshop, Wed., June 21, 7-8:30 p.m., $35, Upstairs at Mad River Cafe, 126 Chestnut St., www.moxieinthecity.net.

Let's talk about sex, baby. Fresh off earning her master's degree in human sexuality, Playgirl advice columnist Jamye Waxman (below, not the gnome) wants to teach Philly women a few of her mouthwatering tricks.

As part of the 90-minute fellatio workshop, the sexpert will be discussing not only techniques but how women can build their sexual confidence, rid themselves of performance anxiety and make blowjobs a win-win situation for both partners.

"The brain is the most powerful sex organ," says Waxman. "Sex is something we all experience even if we don't go to school for it."

And while most of us are degree-free when it comes to the old peel-and-suck, Waxman encourages open discussion beyond the classroom. That's assuming you don't already have a mouthful.
