He came out as bisexual in 1998 and is active in various LGBT causes and organizations. He was married to actress Hilary Lyon for 8 years and is now married to artist Grant Shaffer. He has stated:
I see a worrying trend among LGBT people, that if you identify yourself in just one way, you close yourself off to other experiences. My sexuality has never been black and white; it’s always been gray. I’m with a man, but I haven’t closed myself off to the fact that I’m still sexually attracted to women.
