Is there a database of a sort for doujin and commericial non-vn erogames?

[saufall]

I've first come to know this kind of game around years ago. My first game of this kind is Parasite City which is a classic (a shooting adult game where the blonde is raped by parasites). There were not so many non-vn adult games like adult rpg or action or shooting games back then, and it was easy to find them. However now there are so many i don't know how to choose. I wonder if there is a database of sort that catalogues all or at least most of the doujin or commericial adult games that are not VN and are not included in the VNDB. For example, if i want an ero action game with a cute boi being raped by beautiful, lusty milf, I can use the database to find it. Or anything that serves the same purpose. Thx.
PS: Does DL site or DMM work well for this purpose? I cant understand Japanese perfectly so it would be of great help if someone can give me some hints on utilising DL site of DMM to search for non-VN adult games.
