'I'm Married To A...' Sneak Peek: Ali And Lorne Have An Insatiable Appetite For Sex

[mtvn_player vid="922316" autoplay="true"]

Live-in couple Ali and Lorne use their home of San Francisco as a playground for "second base parties," which is likely not something you took part in back in your Little League days. "I just have an insatiable appetite for sex," Ali explains. "So I like to date like three guys at a time because then no one person is exhausted." And everyone is okay with that?

On the season finale of I'm Married To A..., we meet a polyamorous couple, who explain how they step outside their relationship to meet their physical needs, ultimately allowing themselves to fall in love with multiple people to capitalize on the "abundance" of emotion they have to spare. To practice this lifestyle, honesty is the best policy, and making sure you define certain feelings and specific "bases" in the same way is extremely important. Get to know the couple by watching a first look at Tuesday's episode above.

Catch the season finale of I'm Married To A... on Tuesday at 10/9 C.
