David Schwimmer Got Creepy About Anal Sex On Lisa Kudrow's 'Web Therapy' (VIDEO)

On Lisa Kudrow's Showtime series "Web Therapy," guests are encouraged to just go with the flow. However, sometimes things can get a little out of hand and awkward. When Kudrow stopped by HuffPost Live, she said things got a bit uncomfortable when her former "Friends" co-star David Schwimmer came on her show.

On "Web Therapy," Schwimmer played a man who witnessed an affair between his father and Fiona (Kudrow) when Fiona was in college. Schwimmer's character was then advised by another therapist to have sex with Fiona in order to purge himself of the scarring memory.

"Schwimmer was so creepy. The character he chose got so creepy and was insisting on anal," Kudrow said through laughter. "Can that be on Huffington Post?"

The subject matter didn't make it awkward for Kudrow, but his insistance on the act did. "It was more that his character was so insistant. 'It's going to happen, whether you like it or not.' Well, OK, now that's rape."

"Web Therapy" returns for a third season on Tuesday, July 23 at 11 p.m. ET on Showtime.
