Here is your scientific answer:
Reproduction
Mating earthwormsEarthworms are hermaphrodites (both female and male organs within the same individual) but generally cannot fertilize their own eggs. They have testes, seminal vesicles and male pores which produce, store and release the sperm, and ovaries and ovipores. However, they also have one or more pairs of spermathecae (depending on the species) that are internal sacs which receive and store sperm from the other worm in copulation. Copulation and reproduction are separate processes in earthworms. The mating pair overlap front ends ventrally and each exchanges sperm with the other. The cocoon, or egg case, is secreted by the clitellum, the external glandular band which is near the front of the worm, but behind the spermathecae. Some indefinite time after copulation, long after the worms have separated, the clitellum secretes the cocoon which forms a ring around the worm. The worm then backs out of the ring, and as it does so, injects its own eggs and the other worm's sperm into it. As the worm slips out, the ends of the cocoon seal to form a vaguely lemon-shaped incubator (cocoon) in which the embryonic worms develop. They emerge as small, but fully formed earthworms, except for lacking the sexual structures, which develop later. Some earthworm species are mostly parthenogenetic, in which case the male structures and spermathecae may become abnormal, or missing.

Measuring the penis when it isn't erect is pointless, since the length and bulk are affected by various temporary factors, such as the ambient temperature. Even the largest male organ can shrink to virtually nothing if the man goes for a swim in cold water. However, at normal temperatures a non-erect p enis usually measures between 8.5 cm and 10.5 cm (3-4 inches) from tip to base.

The average figure is about 9.5 cm (3.75 inches). Of course, it's true that some men have big penises and some have smaller ones, just as some men have small feet and some have big feet, but the measurement is not – repeat not – an index of virility.

it is a hermaphrodite having both male and female sex organs. During mating each worm will fertilize the other.

Do you mean earthworms? There are many, many different types of worms, and (depending on the species) they can either be male, female, or both.

every worm is both, containing both female and male reproductive organs in there system. When mateing they connect heads and pass sperm back and forth the sperm is stored in sacs.....

It's an hermaphrodite, that means it's both male and female.

im not 100%sure their all hermaphrodite that is they have both female and male sex organs-some are capable of asexual reproduction like for example in tapeworms and some are capable of sexual reproduction like in eartworms.as far as i know organisms in the phylum plathyhelminthes are hermaphrodites even phylum annelida but im not sure about nematoda.
