Out actor Jonathan Groff says that HBO's upcoming finale for Looking includes “the most intense sex scene” he's ever done.

HBO abruptly canceled Looking after its second season but promised a special to end the series.

The show follows the lives of three gay men living in San Francisco: Patrick (played by Groff), who came to the city to find love, Dom (Murray Bartlett), a waiter looking to fulfill his father's dream of owning a successful restaurant, and Agustin (Frankie J. Alvarez), who struggles with his art and relationships.

Season 2 ended with Groff's video game designer character Patrick questioning whether he should stay with his boyfriend Kevin (Russell Tovey) or pursue a relationship with Richie (Raul Castillo).

There's a lot of sex. I don't want to say who it was with, but I just shot the most intense sex scene I've ever done,” Groff told BroawayWorld.com from San Francisco, where he is filming the finale to Looking.

One of the cool things about Looking is that after the first season, a lot of people – shockingly, liberal, open artists in New York and L.A. – said they didn’t know that gay people could have sex while facing each other.”

“The show illuminated intimacy in sex [between men] without being porny or salacious. Those scenes felt very real and true to life. I was excited to do them,” Groff added.
