I'm not sure about fetish, but I do know if I had the chance to be a vampire, and they weren't of the sparkly variety lmao, I would totally go for it. I would love to have the strength and power, the speed and other abilities and honestly, as sick as it may sound, I'd love to have the power of life and death over my prey. To know you have the power to take a life in a matter of moments, and be compassionate enough not to take it... that's sexy. But I think it's more of a fantasy than a fetish in my case.
