The Picture of Dorian Gray by Oscar Wilde (The Uncensored Edition)
"The novel tells of a young man named Dorian Gray, the subject of a painting by artist Basil Hallward. Basil is impressed by Dorian's beauty and becomes infatuated with him, believing his beauty is responsible for a new mode in his art. Dorian meets Lord Henry Wotton, a friend of Basil's, and becomes enthralled by Lord Henry's world view. Espousing a new hedonism, Lord Henry suggests the only things worth pursuing in life are beauty and fulfilment of the senses. Realizing that one day his beauty will fade, Dorian (whimsically) expresses a desire to sell his soul to ensure the portrait Basil has painted would age rather than he. Dorian's wish is fulfilled, and when he subsequently pursues a life of debauchery, the portrait serves as a reminder of the effect each act has upon his soul, with each sin displayed as a disfigurement of his form, or through a sign of ageing."

We chose this book because hey, how could we lose? Oscar Wilde is a BAMF and there's a version of the movie made in 2009 that has Ben Barnes (The face claim of Twittibal OC Mark Davenport) cast as Dorian Gray. And, from the looks of it, there's plenty of sensuality.
