yeah, I've had this skin condition all my life, great to finally know the name of it.

it's great for keeping your arms warm if you're stuck out in the cold without a jacket. as far as sex goes, it doesn't seem to be a problem for me there, unless I'm just really rough with my skin there. shaving anywhere on my body is a bitch though. my face and elsewhere will swell up if I try to get in close, especially with a dull razor. then the itching starts.
