Two characters that used to be a couple broke up. They got bored of each other or argued too much, he just wouldn't put the seat down, she used too much toilet paper, whatever. Emotionally or mentally they didn't think they were right for each other. Sexually, however, they still get along just fine.

They may only get to kissing each other or get further than that, but as long as they're reinitiating a physical relationship it's fair game. It can naturally take on a variety of forms, as people are complicated; it may just be sex and friendship, it may be a pattern of hooking up, swearing to never see each other again, and hooking up again, or they could go back into a relationship.

May lead to getting back together, particularly if it starts after a separation or after they've moved on to other people for added drama/comedy. Naturally, a common sitcom trope.

Subtrope of Amicable Exes, where they're really amiable. Supertrope to New Old Flame.

Examples of Sex with the Ex include:

  • My Name Is Earl: Earl's wife Joy divorced him in the first episode and those early episode had a very rocky relationship.

Interestingly enough, their activities did not end because of romantic complications, but because Barney was secretly in love with Robin at the time, and when Ted figured this out (due to Barney's not-so-subtle attempts to stop them from fighting and therefore having sex) he immediately called off his arrangement with Robin and allowed her to believe it was because he was afraid he'd redevelop feelings for her.
