What's the deal with blue balls?

This week on EMandLO.com we asked Doc Joe what's the deal with blue balls. And turns out his solution is the same one we'd give: just rub one out, dude! So what's your feeling on blue balls -- men, is it something you mostly grow out of, or still a painful problem? Ladies, have your partners ever complained of it? Also, ladies, do you ever get blue labes?!
