The majority of gastropods have internal fertilization, but there are some prosobranch species that have external fertilization. [4] Gastropods are capable of being either male or female, or hermaphrodites, and this makes their reproduction system stand out amongst many other invertebrates.
Some gastropods have separate sexes, others are hermaphroditic. Some hermaphroditic groups have simultaneous hermaphroditism, whereas some sequential hermaphroditism. In addition, numerous very different mating strategies are used within different taxa. This article currently focuses primarily on the mating habits of air-breathing terrestrial slugs

The male sexual organ of an adult banana slug is quite large in proportion to its size, as well as compared to the female organ. It is possible for banana slugs, while mating, to become stuck together. If a substantial amount of wiggling fails to separate them, the male organ will be bitten off (using the slug's radula), see apophallation. If a ...
Preserved specimen have a length of 25–30 mm and a width of 6–8 mm. [3] The weight of adult slugs ranges from 991.2 mg to 3308.0 mg. [4] Reproductive system: The penis is rounded, and half as long as the epiphallus. [3] The epiphallus is slightly widened and truncated (as if cut off) at its end.
Gender identity (despite what the gender binary suggests) does not have to match one's sex assigned at birth, and it can be fluid rather than fixed and change over time.
