Masters of SexIt's 1966 and the sexual revolution is heating up — thanks, in part, to the stunning sex study completed by Bill Masters and Virginia Johnson.

Season 3 of Showtime's "Masters of Sex" begins five years after last year's finale, with collaborators/lovers Bill (Michael Sheen) and Virginia (Lizzy Caplan) ready to take their published study on the road.


Still in the picture is Bill's wife, Libby (Caitlin Fitzgerald), though she seems to have undergone her own sexual awakening over the years. As the trailer shows, she was always curious about "what it felt like ... with you" — meaning Libby!

This season introduces a major new character played by former "Good Wife" star Josh Charles. Daniel Logan is a businessman looking to sell the "smell of sex" in a bottle, and his relationship to the couple — particularly Virginia — becomes complicated. We'll also meet Virginia's parents, as played by Frances Fisher and Michael O'Keefe.

"Masters of Sex" season 3 premieres Sunday, July 12 at 10 p.m. on Showtime.
