I also have these voids at night often and sometimes after breakfast. BUt they could happen later in day also. I'm using abena m4 brief for many years.
I think that many men who used diapers growing up and at night, and esp when they didn't manage themselves. They are likely sexually undeveloped. many disabled men in diapers have no sexual life.
I use regular razor as well as an electric razor on the diaper area minus the top public hair. I do this every other day. I also use a barrier cream which I apply just a little - coloplast and it takes cares of rashes and chaffing.
I roll up from front of the brief into the back and do it tightly keeping mess and wipes in the brief. They use the tapes to tightly close the brief and then put into a plastic bags and tie.
I lay on a chuxx and just wear adult diaper and waterproof cover. I sometimes tuck a tee shirt into the waist of the plastic cover (gary) to not have elastic marks.
Have you been in diapers your whole life? Do you change them or alert a caregiver to change you? Can you tell when you have soiled? I haven't been in diapers my whole life.
