Hypothetically, would mind blanking be able to work on men as well?

Sure. 

I believe there’s a caption about it buried here in the nearly 5000 posts, however, femdom doesn’t get reposts as well as maledom and barely sell, so I don’t write it much. That’s the out-of-world reason.

In world? It’s a world where women are mind blanked, mostly by other men and sometimes by other women. That’s what the Mind Blank Shops and Build A Bitch stores markets there are geared towards. That’s what sells in-world. It’s also what the society in that fictional world accepts as normal.
