If I could have sex with any character on Downton Abbey, it would be Molesley. He seems like he's the type that is most likely to try and would probably go down on a woman. The rest seem like they would be selfish. Certainly Mary (that goes without saying) . Definitely the Tom Branson (he'd make you think he'd be willing to go down on you but then at the last minute would make some excuse—like it reminded him of his British oppressors). And Mr. Crawley, he would harrumph at the very suggestion. But Molesley. He would look at you eagerly, apologize for his impertinence and tackle the task with the kind of dedication that only he can muster.
