I have learned this way. When I was in 5th grade I accidentally peed on myself in front of everybody in an after school program. I was so embarrassed and I stared to cry cause I didn’t know what to do. First my mom was very angry at me and wanted to punish me but she realized how stupid that was going to be. I washed up and we had a big talk about the responsibility of me being a carrier of a penis and how exactly do I use my tool. She just simply told me “Sometimes toine, you just got to hold it in, but if you have to,allow yourself to pee only a little, bit resist the urge to let it all out”. Ever since then I trained myself everytime I peed. I would pee a lil, than hold it in fir 30 seconds, until my desire to pee went from my dick feeling like it was going to jet fire my piss to my need of peeing just went away. After 5 years of practice by high school I’ve mastered burst peeing, and I never owed on myself since than. It even comes naturally now sometimes. Never peed on myself since than.
