When I was 12, several months before I had my first orgasm, I started producing precum. I started noticing this slippery, gooey, crystal clear fluid that would ooze out of my young erect penis whenever I was playing with myself for a while or thinking about "sexy things". I knew that guys produced sperm and girls got pregnant by a guy putting his penis in their vagina and leaving his sperm there. So I was absolutely sure that this must be my sperm!! (Then a few months later, when I was was stroking it and I actually did come, WOW!! It squirted all over the place and it was different! It was smelly and a little cloudy! So...then what was the other stuff???)

I remember one boy I used to masturbate with when I was 13 used to be really grossed out by my precum and wouldn't want to touch me when I started getting "juicy" as he'd call it. He never produced ANY precum, so again I was confused what this gooey stuff was that came out of me but didn't come out of him. (But when we'd masturbate eich other, we both would shoot about the same looking trail of semen squirts onto our bellies.)
