From what I remember in science class years ago the male squid is usually called a sneaker squid.
Or also Sneaker Male Squid.
Male Squids have small penises just humans have penises and they mate using their penis into a female squids vagina.
Squids reproduce sexually like dogs, cats and humans do.
In male squid, sperm is produced in the testis and stored in a sac.
When the squid mates, the male uses a special arm to transfer packets of his sperm into the female's mantle cavity or around her mouth, where the eggs are waiting.
