Im assuming that you have stopped the hair treatments. Hopefully the side effects will go away, if that is what's causing the problem.
Theirs not to many people that are experiencing your problem. Man, I wish there was something I could say to help! I think their are more men that are willing to admit with the leaking problem that you're having, to some degree. The kegal suppose to help, but probably with minor leakage. What has helped me is, standing at the toilet for another 30 seconds.
What ever that haven't drained, usually does within that time. Part of our problem does seem to be, us rushing from the urinal/toilet.lol..As we get older, we have to learn the patience of waiting for that last drip..
In the mean time, keep our hears open for tips to help us out.
