I think my nickname gives away my fetish, as if I hadn't mentioned it enough times already.
Anything tight really.... tight jeans, but also tight sports shorts, speedos, underpants, singlets - as long as they fit the male contours and show them off.
I am also into spanking, or more accurately into being spanked. Had it several times over the years, though not very often. I love taking the strap or paddle on the arse of the jeans or shorts.
