A 12 year old boy producing sperm while orgasming is definately not a record. 12-14 is average, which means there are people who go above and below the average. In Western countries puberty is starting ealier and ealier at least because of better nutrition and maybe other reasons.

What you think about while masturbating you will be attracted to. At least from my experience no. I was a boy orientated pedophile, BL, before I was masturbating. I had yfs before puberty and before I masturbated. Hell this premise would mean that everyone is asexaul before their first self induced orgasm.

Oh I'm aware that I'm not addressing the important part of your post but others have done that and I wanted to point out something no one else has mentioned.
