Twitter-based sex chat program Sex Talk Tuesday (#SexTalkTuesday) welcomes Nina Hartley as a special guest moderator for its upcoming show on Tuesday, December 3.

“We are thrilled and honored that Nina will be joining us as a guest moderator on Sex Talk Tuesday,” says Angie Rowntree, publisher of Sssh.com. “She is truly an icon and role model. This is going to be a great!”

Nina Hartley has been a driving force in the adult industry for nearly three decades as an actress, director, sex educator, feminist and author. She has been a tireless, outspoken advocate for sexual freedom and promotes a healthy, sex-positive culture. Hartley strives to change the negative perceptions of adult entertainment and sex itself, believing instead that porn has the capacity to empower women.

Hartley has appeared in hundreds of mainstream and adult movies, including Missing Pieces and Boogie Nights. She has also appeared as a guest on numerous talk shows such as The Phil Donahue Show and The Oprah Winfrey Show. Hartley also produces a no-nonsense sex advice series called Nina Hartley’s Guides‚ available at her store on Nina.com.

A fun and provocative Twitter-based chat held every 1st and 3rd Tuesday of each month from 4 to 5 p.m. Eastern Standard Time, Sex Talk Tuesday is hosted and coordinated by Sssh.com, the web’s premier destination for erotica made by and for women.

Each session, a guest moderator asks thought-provoking questions to a large and active group of participants, who send hundreds of tweets during each round of Sex Talk Tuesday. The result is a lively and entertaining discussion that invites participants to be open and candid with their thoughts and opinions on sex, life, love and the humor of it all, in a way that fosters a supportive and compassionate environment for the conversation.
