Interesting question-- I once had him wear a wig I was cutting/styling (couldn't use a wig block, needed something with a neck). I was turned on by it, but I think the incident make him feel very icky. I keep thinking he'd look nice in a hairpiece (doesn't really need one right now, but some extra hair volume on top would go well with his head shape). I enjoy giving him a haircut from time to time BTW.
