i swear this is the truth, i used to know a guy that had a heavy object drop on his head and swears he got turned on by it after the pain subsided a little, he reckoned he would fantasise about how women would be mean to him and hit him over the head with an ornament or something ever since that day.
I suppose playing guitar very loud and fast isn't meant to be sexy in itself, but it usually gets me going. However, it does help if it's been played by a young, long-haired chap, so I dunno...
my boyfriend was eating a peach and cutting chunks of it off with a knife. They way that he cut made the chunks of peach stick to the knife and he was eating them off the knife. I don't know why, but it was just really sexy.
That bit in a fish called Wanda when John Cleese is looking at Jamie Lee Curtis in the car park, after she recognises him as the "famous" Archie Leach. I sometimes see the bloke I fancy give me that look, and it makes me GO in my PANTS!!
Seeing my boyfriend reading, really into the book he's reading turns me on. He looks so serious and concentrating so hard (he normally reads quite heavy going stuff, biographies and historical stuff) I feel obliged to give him some fun. I was also in the same exam hall as him last year and every time I looked to my right I could see him with that same look on his face. I had to drag him home rather quickly afterwards ^_~
A scene in the remake of Cape Fear really does it for me. When Robert De Niro gets Juliette Lewis in that room in her school and he makes her lick his thumb. The fact that she's young and he's a psycho makes it wrong to be sexy?!
