Most terrestrial snails are hermaphrodites, so it’s more like they can only mate with their own sex. But it’s a bit more complicated than that; they typically produce sperm earlier than they produce egg cells, to discourage self-fertilisation, so you could argue they start male and end female.

Youth to inject random new genes for testing and age to work with what’s tried and true …. Huh.
