you can share if you want to but you dont have to.
anyways i suprisly havent played any nsfw game sin quite some time, i guess its a form of entertainment for me that adds more to a story like spice, if that makes sense but its a good way to play games i guess.
They provide small dopamine rushes every time you unlock new scenes or reach a certain milestone with characters. Plus there are some games that are legitimately fun mechanically, and it almost feels like the NSFW part was tacked on as an afterthought.
