"It's miserable when you have to do a sex scene. Unless you're a porn star or unless you're jacked up on something... it's impossible to do these things and feel good about it... but you are wearing a merkin... It's a pubic wig and somebody sits there and handknits, like, these little wigs, a hair bikini." Actress Lucy Lawless on the full-frontal sex scenes in racy TV drama SPARTACUS: GODS OF THE ARENA.
