The series–the cremaster is a muscle connected to the testicles–illustrates Barney’s obsession with sex. Not “Eyes Wide Shut” sex. More like “Your Reproductive System,” stoned on androgyny and postmodern decadence. Yes, it all sounds too weird. If you just chill, however, and let Barney’s films wash over you, the question “But what does it mean?” won’t even occur. Until you dream about them.
