Talk to Hayden and ask to rent a room for the night. He'll quote you a price, then quote you a slightly higher price to get a female prostitute to be in your bed (it might be his wife, I'm not sure, never took that offer), and then you can ask him how much to have him join you. If you pay his price (40 gold, I think) you can sleep with him. Normal scene is he fucks your character, but if you're male and you have a high Bareshade Hero score (higher than your bitch score) you can top him. Either way you see his sprite naked.
