Disclaimer: This is a mixed bag of guys. I can't explain why one person turns me on and another that looks almost the same doesn't. I also have a lot of older guys in my list (though my husband is 3 yrs younger than me). It's a mystery though I can say that a sense of humor , an accent or playing James Bond can tip the balance.
Daniel Craig: The contrast between his body and his lived in face is hard to resist. He's the only one on the list purely for aesthetic reasons. I noticed him first in Lara Croft Tomb Raider, thought he was a great pick for James Bond and just recently fell completely in lust with him during Flashbacks of a Fool (good movie with some serious thoughts about death and friendship wrapped in lots of Daniel nudity.)
Pierce Brosnan: I've had the hots for him since Remington Steele and he just gets better with age. I was seriously upset that he had to defer to Timothy Dalton the first time he was tapped for James Bond. He was a great Bond.
Sean Connery: I don't even know what to say here. It just seems obvious to me that he is incredibly sexy at any age. Part of it is the accent - no one has a better one. Despite the plaudits given to the 2 above, Connery is the definitive James Bond.
Hugh Jackman: What do I need to say? He's gorgeous, funny and has a great accent.
Jon Stewart: Adorable, outrageously funny and scary smart. I think he's sexy as hell AND I'd want to marry him if I didn't already have a fantastic guy.
Dwayne Johnson (AKA The Rock): I can't explain this pick. He just works for me. Maybe the (delusional) belief that I would always be safe. I don't know. He does have a fantastic body and an interesting face.
Steve Martin: Really funny, courageous, scary smart and yet down to earth. Another one who is sexy to me because he's marriage material. Or seems to be.
Brendan Fraser: This guy has it all. Great body, good looking, funny/goofy and smart. School Ties is the first time I saw him. Fantastic performance and he was such a cutie. He is too die for in the Mummy series.
I was going to try for 10 but this is as far as I could get. No one else rises to the same level as the guys above. I couldn't rank them because each one is uniquely sexy to me.
