I think you're asking about "withdrawal." It doesn't work because there's usually something at the tip of the penis.
it is usually never effective, because even if he pulls out before he ejaculates, there is still a little chance that some of his semen is inside you, and you can still get pregnant.
No!
Not at all!
There are a few different behavioral methods of birth control. Three examples are coitus interruptus, the rhythm method or "fertility awareness," and abstinence. Coitus interruptus has a variable reliability, the rhythm method is better, but abstinence, where possible, is 100% effective. Some experts do not consider abstinence birth control, and some do not consider coitus interruptus birth control.

The method of pregnancy prevention in which pre-ejaculate plays a role is withdrawal, or coitus interruptus.
That must have been Onan, who "let it spill on the ground", i.e. it seems he practiced coitus interruptus.

The period can act weird like that, it's quite normal. But the so called "pull out method" aka coitus interruptus in Latin? There's a old joke going; - What do you call ppl who rely on coitus interruptus? - Parents! Even if he pulls out he still have pre-cum and that has sperms in it too. Many women get pregnant that way.
Coitus is coitus.
Not safe since there's always pre-cum.
