Well this is the most I've ever masturbated, wasn't even "horny", just did it cause I was bored and wanted to see how much I could.
not that I am aware most guys can orgasm a bunch of times in a night, depends if they want to, for some it does require waiting a bit, like 20 mins
The seamen amount stayed about the same, it wasn't a low amount either, and it only took me 5-10 mins max each time.
Ah Yes, more beauty of youth. I remember the time in my teens when I would beat off so much my dick would start hurting. Of course at your age, resolution from one orgasm to another is very short. Wait for six decades. Only good for one a day any more. Maybe two if I really get aroused, but for regular JO sessions usually just one. Bummer. (BTW, as for that speed thing. When I was your age I used to marvel at how fast I could squirt but you will soon learn that speed to orgasm is a disadvantage, especially if you are doing girls. See how long you can stay aroused without shooting off.)
Haha! Ive got ya'll Y-chromosomes beat, 23 times in one night. Of course one of those was sex, though.
