Can a 12 year old have semen?

Technically its called ejaculating, and yes i am twelve and have ejaculated. don't worry if you dont it is pretty rare for a twelve year old

well im 13 but when i was 12 i could ejaculate

Sperm does not appear in semen until the boy have started puberty so if he has at 12 he can. Otherwise no.
