I've been wearing progressively more protection for the last 25 years. It started with dribbling with no warning and I used pad inserts in my briefs. As the voids became stronger and without warning, I started using a Depend pull up. They held one or two wettings. I went through ever thicker and thicker pull ups.
Now I buy very thick disposable diapers by the case. Usually I start the day prepping a diaper with a maximum Poise pad. I purchased a device that pokes holes in the pad's backing. Every few weeks I modify a batch of pads as boosters.
Wearing a onesie extends my wear into late afternoon. By then my diaper has soaked up several wettings and weighs about 4-6 pounds. I then change to a high capacity diaper without a pad. That gets me to bedtime. Overnight I wear a cloth diaper and plastic pant.
After lots of tests, the cause seems to be genetic neuropathy causing degradation of my nerves from the end of my spine to the tips of my toes. It's very sporadic - nerves fire off with pain here and there. Some days not much, other days a great deal. It affects my bladder causing leakage without much feeling and no warning. Most of the time I am totally unaware of peeing.
As I've lost some feeling in my penis, I've modified by masturbation with increased rubbing on my scrotum and perineum; and by adding anal play. Currently I have a low grade prostate cancer which is being closely watched. I'm holding onto orgasms and ejaculations as long as possible.
Thankfully, the nerve condition has not yet affected my bowels. It does affect my leg muscles and leg bones.
There are cases of the same nerve loss with several of my cousins with whom we all share the same grandparents.
Diapers provide me with a sense of security and comfort. Over the years, I've stopped wearing plain old white diapers and clear plastic pants. Now I enjoy colors and patterns. At least two doctors (dermatologist and urologist) have favorably commented on my accommodation with my condition and on my selection of diapers and onesies. One even looks a bit jealous. But I've never said so to him.
I take a large package of disposable diapers with some plastic pants when I go into hospital for elective treatments. I usually perform my own changes. Occasionally I need help which is readily given. I've received some interesting comments and questions when I move around the hospital for testing - MRI, treadmill stress tests, etc. Most people ask where I get my colorful diapers. They only see the hospital-issued diapers for adults. Everybody is very accepting and never critical.
Thanks for reading my too-long answer.
