Our guest on The Playboy Advisor Show on Playboy Radio (Sirius/XM 99) on Wednesday, April 7 at 1 p.m. EST / 10 a.m. PST (with a repeat at 6 p.m. EST and 3 p.m. PST) will be Stefanie Iris Weiss, author of Eco-Sex: Go Green Between the Sheets and Make Your Love Life Sustainable , who will talk about how to keep your sex life all-natural. We’ll also speak with Janice O’Connor, who with her husband invented the Earth Angel, a vibrator that requires no batteries or electrical outlet because you crank a handle to power it. And, as always, we’ll go Inside the Sex Lab for the latest developments in sexual science, present the Big Hard Sex Question and answer your many letters to the Advisor.
