I can relate to much of what you describe. For me it began about 3+ years ago when I occasionally had some post-void dribbling. Waking up in the night and needing to go started happening on a regular basis too. About 2 years ago I started to have trouble after holding for a long time (stuck in a meeting or in traffic) when I finally got to a toilet it would take several minutes to get the flow started, or it would start and stop several times before my bladder was empty. Sometimes even after being sure I was finished, tucked in and zipped, the occasional dribble might be more than just drips! I had the same trouble at night, taking sometimes 5-10 minutes before getting back to bed.
In the last year or so the frequency during the day has increased to every 30-60 minutes, and the time between feeling the urge and can’t hold-any-longer keeps getting shorter. I don’t seem to have any trouble getting the flow started anymore. In fact, in spite of heroic efforts to hold, I begin leaking within a few minutes if not seconds after the initial urge. A few times I have gotten no warning at all...feeling nothing until I feel dampness after having leaked, or that I’m actively peeing. At night I can rarely make it to the bathroom in time. I start wetting as soon as I wake up, and a few times I’ve awakened mid-wetting.
As of 6 months ago when I last saw my doctor, (a men’s health specialist) he can’t find any cause other than enlarged prostate, which he says is still within “typical” range for my age. No infection, no blockage, no nerve damage. He was totally up front about treatment options and their side effects, and left it up to me to make the “quality of life” decision. I would rather deal with moderate incontinence than risk erectile dysfunction or a plethora of other problems.
I am not an AB and not really DL either, but my spouse and I share a bit of a pee fetish which makes this situation not entirely burdensome.
