When I said "well designed" I was more referring to outward appearance. My game recommendations were sarcasm, in case you missed that. They're games about prostitution without NTR. Not trying to criticise the games in any way.
Sure virgins are great and all, but I would think the latter is more important. For all the aforementioned games, all the 'prostitutes' wouldn't be doing that in an ideal world. They're all victims of circumstance. And hey, if that's still not your thing, that's perfectly fine. 90% of the dialogue choices on the Chika route as of v0.3 is literally progress route OR end route. And if her very presence disgusts you that much there's always the exit.
And yeah non-virgins crop up in many AVNs as you say, and surprise surprise, real life too, its not so much about what I find boring or interesting, I was just making a jab at people with unrealistic expectations.
