I was a consistent bedwetter until almost 13, but puberty seemed to take it away completely. I don’t think I had a single accident between the ages of 13 and 17.
But it turns out I also was a sporadic bedwetter. I joined the Marine Corps at 17 and experienced probably five or six bedwetting episodes during Boot Camp, most likely due to being extremely exhausted. Somehow I got away with it with only my bunk mate finding out, and it was never an issue after that for the rest of my time in the military.
Then in my early 20s, I got married and I had another accident. Soaked the bed, I was humiliated, but my wife was very understanding. From then on, I would have an accident every other year or so, but started to also have those times where I woke up in a panic because I realized I was peeing and limited the damage to wet underwear.
About six years ago we were about to buy an expensive mattress, and after a bedwetting accident we both decided maybe it would be better for me to wear diapers at night “just in case” rather than risk destroying it. Even sporadic accidents like that can really ruin a mattress.
What OP described happened exactly to me. Within 3 months I was waking up in a wet diaper once a week, and within 6 months it was probably 3 to 5 times a week. I don’t know the science behind it, but it seemed like my mind subconsciously knew I was protected and didn’t bother to wake me up anymore when my bladder sent the signals.
Most of the time I don’t mind being back in diapers, there’s a sense of comfort and nostalgia that comes from my early bedwetting days. But given the choice, I would definitely prefer to not have to worry about it. My wife is still awkward about it, so she doesn’t really talk about them or touch me when I’m wearing them. It has really affect in spontaneity in our sex life. I’ve tried to encourage her that even if I am “ready for bed” that doesn’t mean we can’t make love, but that doesn’t seem to work out.
So ultimately, yes, I understand OPs concern and definitely recommend talking to a doctor. Apparently I have issues with retaining urine, so the Urologist now has me on Afluzosin which is supposed to relax the bladder neck. It might be something as simple as a pill that takes away any risk of intermittent accidents.
