It's been 9 days, my balls are already needing some relief. That, however, is more than a month away. The only thing for sure is that a multi-month experience beginning later in the year will be interesting.
Being away from home this week isn't making things any easier. Lack of the normal distractions of home only leaves me with more time thinking about the relief I'm unable to get.
The device is reasonably comfortable if I'm not trying to get hard. Use of ample lotion is keeping chafing away. From a comfort standpoint, it could stay on for a long time.
I'm thinking of ordering the Birdlocked device for next time. It appears that the silicone may be more comfortable than the hard plastic of the CB2000.
