I see.... if it's hard to find a game, that is a problem. So, as long as you have the link, you can find it? If so, might have to promote elsewhere if this isn't resolved.
I read on reddit r/lewdgames that someone had created a website with some games (of course, not all of them. It is basically just their collections). There are a few, one being loop-io.dev. Keep in mind that these are made by the community and it's just a way to find adult games from itch.io, not buy them.
Example:
Clicking on "Play on Itch.io" will take you to the official itch.io page for Once in a Lifetime by Caribdis.
