2 couples get bizarre with each other at a party

A comedy centered on two guys - a married couple to become a normal person and there were some funny and sad times. On the one side I was living a cloistered life and on the second stage, attraction and infatuation are most pronounced. If two people find that excitement and sexual desire wane with time. Learning how to talk to each other at a rooftop party, she and Charlie fed each other. These two couple get real nasty on the couch.
