Patrick Dempsey is ''celibate''.
The 'Grey's Anatomy' actor - who has children Tallulah, 10, and twins Sullivan and Darby, five, with second wife Jillian - is dedicated to cycling, even shaving his legs to improve his performances, and says giving up sex has helped him become even more focused on his training ambition to ride 100 miles.
He said: ''Yes, leg shaving has done wonders for my riding; now that I'm celibate it's easier to focus on my training plans. Seriously, I want to ride a century; that's my goal. My longest ride so far is 75 miles.''
Patrick - whose hunky 'Grey's Anatomy' character Dr. Derek Shepherd is nicknamed McDreamy - credits cycling for helping him cope with stardom.
Speaking to the January/February 2013 issue of Bicycling magazine, he said: ''Psychologically, getting back on the bike really helped me. It was hard to weather the success of 'Grey's', but I found I could go for a ride and get centred. Cycling also taught me a lot about managing discomfort. When you leave your comfort zone, you learn how to manage your emotions and to stay focused.''
And the 46-year-old star dreams off opening a cycling shop where other riders can go to hang out.
He said: ''I'd love to open a bike shop in Mailbu that's a hangout for cyclists. There's nothing like that out there.''
