so I guess we can go back to the main topic of anatomically sex scenes, isn't weirdier that that none of the male characters have erections during the sex scenes, there's barely any twitching in the lower area, I'm a guy, I should know, it twitches a couple of times before a full erection,
Not weird. An M rating would never get away with that; it would be rated Adults Only, which would significantly impact it's ability to release globally, and of course players that would buy it. Most things rated A are basically just porn.
