Is it normal for a straight person to have a strong thing for same-sex hands?

As I said, I'm straight myself, but I can't help getting hot when thinking about beatiful hands of people of my own sex. I'd love them to touch me all over my body, but I wouldn't like to get intimate with somebody of the same sex, it's just their hands. I even paid somebody to lick and caress their hands, put rings on their fingers... I'd also like to write naughty things on those hands. I used to take photographs of strangers' hands when they weren't looking. IIN?
