This is one of the more fasciating modifications I’ve seen. The person (who already has a split glans and other heavy work) wanted an aggressive curve to the right in his penis, so he’s been making small injections of 70% alcohol into the cavernosa on that side. This is after the second 0.2ml injection, with two more planned. Because it kills off some of the tissue, which then scars together more tightly than it was before, the result is a curve.

Maybe someone with a really long penis will attempt a corkscrew.
