You classify this Game as "safe and Mainstream"? Holy Shit.. You may try "Karlssons Gambit"! You may like it.
And it's being contrasted with anal.
Like, watersports, leaving your daughter in suspension bondage overnight, permanent disfigurement and making out to people burning alive? Safe and mainstream.
Anal? Dangerous and controversial.
That said, Karlsson Gambit is both great and edgier than this game, so +1 to that recommendation.
