Almost anything can be a fetish. Besides the ones you usually think of (B&D, S&M, leather, latex, cross dressing, oiled up, etc.), and the ones people usually shudder at (various body fluids), there are an unlimited number of possibilities.
One guy I know used to get super excited having sex while his two DOGS watched. Uh, OK....
If it doesn't really hurt you, or someone else, I say ... Go for it!
Then again, my favorite model tells me a guy took him to private and then wanted him to strangle himself until he passed out. He wisely said No.
