By the gods, how is Marcurio only BARELY mentioned in here?!
Marcurio is my first and only true love forever in Skyrim.
^I want that. I want it YESTERDAY. Imperials, mmmm.
I must agree with Wildroses about Ondolemar, that Altmer is yummy. I too did the Ogmund quest for him while quite under his spell.
Then, of course, Brynjolf is smokin'. That accent, that voice, that personality. I love it. And courtesy of the 'Dragonborn' DLC, the Dunmer mercenary Teldryn Sero also helps round out the top of the 'sexiest Skyrim men' list. That voice and attitude, not to mention that face...UNF.
I'd also readily include my story characters in this list, but I'll stick to canon men.
