"why does the game need a port--" is a silly question to ask, accessibility is always needed as it impact sales and player count, doesn't matter if it's a minority or not as long as the game devs can handle it. now this is just a theory but nowadays there's more people who use phones than before, phones can handle way heavier games and so there's a lot of people that are browsing on phone than PCs which require setting up, plus you can jerk off to a hentai game in a bathroom lol.

Question was not "why does the game need a port", it was "why people need a port". Most of nsfw games don't need good PC, so "phones can handle way heavier games" definitely not it.
I think reason is that many people who play these games are actually minors, or at least aren't living alone. If you're afraid of being caught, then safest time for this is when you're in bed and everyone at home thinks you're sleeping. Even if someone walks in you can quickly hide your phone and pretend sleeping.
