It is not uncommon for some particularly cruel sorcerers to turn people into "collectors".
Collectors are, to put it bluntly, fuck cubes. The victims are reshaped completely so they're easy to store and transport, and the only features they keep are holes (single or multiple ones). Their only purpose is to collect semen, for that they are to be left alone for some time in a place where some specific creatures lurk, in the hope that they'll be used as fuck toys. It is common for the sorcerers to use pheromones to ensure that the collectors would attract the desired creature. After some time, the sorcerers come back to retrieve the victim, and whatever creature seed they needed in the process.
Depending on the time they were left outside, and the creatures they were supposed to attract, it is quite common for the collectors to get their holes ravaged in the process. Most sorcerers would heal their victim before using them again to ensure that no semen would leak out.
Being turned into a collector is sometimes just done as a punishment, with the victim being offered to a familiar or brutish servants. In these cases, healing isn't in the menu.
