Patrick Dempsey Struggles To Compete With 'mcdreamy'.... Grey'S Anatomy star Patrick Dempsey struggles to compete with his character Dr Derek 'McDreamy' Shepard when it comes to wooing the ladies.The 41-year-old, who has three children with his wife of eight years Jill Fink, insists that playing what many women view as the 'perfect man' isn't easy - and admits he finds it hard to impress his partner.Dempsey says, "I hope I still make her swoon! "Sometimes I think, God, would Derek Shepard do this? Because I am certainly not a perfect male at this moment."Just trying to provide and communicate and let her know how beautiful and important she is to me - I think those things make her swoon."In other 'GreyS' Anatomy related news: star T.R. Knight is happy with his decision to come out as gay, despite being warned it was a 'bad idea'.Knight revealed the truth about his sexuality last year (Oct07) following an incident with castmate Isaiah Washington, who is said to have called the 34-year-old a 'faggot' during an on-set argument with co-star Patrick Dempsey.Knight tells US gay magazine The Advocate, "I remember saying to someone when I got one of those 'don't do it' (comments) - I just remember hearing my voice being calm and saying, 'No, it's going happen. It's going to happen. I'm just letting you know.' "I made the decision to make a statement. I could have not (spoken up). I could have retreated. But I'm definitely happy I made the decision."
