Dh used to shave because of the road rash thing too. Although I've secretly thought it was to show off the definition in his legs.

Personally, I didn't like the shaving because he'd be uber prickly by the evening. I requested he shave right before bed if he was going to keep doing it. Fortunately he's lost most of the hair on his legs below the kneecap and no longer really needs to shave. Why can't this happen to me? But the hair seems to be popping up in other places, so the trade off really wouldn't be worth it.
