My issue with free-use is that it’s inherently misogyny based, but I’d still love to read some world-building (fanfic type thing, or a subreddit) of a world where it’s not just one gender that’s used as sexdolls, but rather both parties require consent still. Essentially a civilized society much like ours, but via some form of regulations, privileges such as sex in public, masturbation, is widely encouraged and popularized, etc.
I guess, by it’s very definition, this wouldn’t be free-use at all, but still, I hope you understand what I mean.
