Damn bro i know the feeling. Has happened many times and it sucks when I'm with a partner or hookup and i bust trying to roll the condom over my cockhead and down my shaft. Pretty humilating having the same stamina i did when i was a teenager
In the back of some high school classes (under the table) I undid/unzipped my pants taking out my erection so I could jack off and not make a mess. Fortunately, I did get the condom on pushing back my pubic and shaft hair so it wouldn’t get pulled rolling it down to the base, without ejaculating first. One time the teacher came caught me as I was cumming, filling it. I was afraid he’d call or write my parents about it, but didn’t.
