I noticed sometimes when riding long distances that when I stopped to get gas that I had some slight drippage (maybe a couple of drops) in the  crotch region. Kind of like when you take a piss in a hurry and you don't quite shake it enough before you put it back in your pants.

It's never happened before but of course I've never had a solo seat before and I do notice when I ride the boys are banging around down there. I'm just wondering if I'm doing some damage or is this normal for solo seat rider?  

Never happens any other time riding or any other activity.

where did you get it from?

I'm going to try that. You know how it is down here in Sorry Vista we don't have much of anything so I'll probably have to order material online.

I was reading other bike forums and it doesn't seem to be uncommon for sports bike riders. I guess that's why they call them crotch rockets. It's seems sport bike riders have problem with their balls going numb. At least I don't have that problem with my nuts. Although my tushy has gone numb a couple times but no pain no gain.

Perhaps the massage from the vibration is 'exciting'?
