Even if the sex itself isn’t particularly weird, there’s still something frightening and exhilarating about hopping in the sack with a deranged killer like Billy Loomis or a violent douchebag like Billy Hargrove.

You want to get down and dirty with Negan? Expect Lucille to join the party, along with the knife he wears on his thigh. They go to levels of freaky you might never have even imagined possible. Of course, villains don’t just get a little freaky in the bedroom. That’s one of the reasons they’re so irresistible.
