First time to mastuburate,, what was the white sticky thing lol?
The sticky liquid that you ejaculated was SEMEN, not SPERM. You are quite right, you are too young to produce sperm at 12. Your semen is made inside your body, by your seminal vesicles and your postate gland. These develop early in puberty, usually at stage G1. Your testicles do not start maturing until stage G2 or G3, and that is when you will start getting sperm in your semen. Sperms are microscopic in size, and the 50 million or more that a healthy guy will ejaculate in a normal load of semen would barely cover the head of a pin. Sperm are transparent, by the way. The milky color of your semen comes from the protein, sugar and other nutrients it contains for the sperm to feed on. So to start with, most boys will be enjoying ejaculations of semen early in puberty, but it will not be able to make babies for a while. Unless you have a microscope handy, you will not be able to tell if there is sperm in your semen by its appearance, smell or taste. There are exceptions though, so be care
