Literally no one ever told me about masturbation
I didn’t ever orgasm until I was 12 and became so horny I was just staring at my always hard dick and poking it several days in a row when I finally just nutted so hard I think I nearly lost consciousness. I was producing semen by that time anyway.
I think I could dry cum when I was 15 by masturbating several times in a row. After my teenage years my nuts generally produced semen so fast that even serial masturbation couldn’t deplete it. These days of course I can’t even really do serial masturbation even on speed.
