Someone way back upthread mentioned it tongue in cheek, but…
…uh, yeah. Long hair on your partner feels amazingly sexy brushing on your arms or back when you’re making love.
And by “you”, of course, I mean me. I love men with (healthy) long hair that touches me while we’re doing the deed. I even love the feel of my own long hair brushing me while we’re doing the deed. And I love to tickle him with my hair. 
Well, when I said it I really wasn’t kidding! I’ve always known (or * strongly suspected)* that this is a big part of the hair attraction and I was just waiting for someone to speak up. Leave it to a woman
I’m not disagreeing; my sexiest lover had beautiful plumage when I met him (and boy did he know it, too). Now he shaves his head and is 100 times sexier. Not that bald is for everyone; I’m just admitting to my own past hair fetish.
