I don't know for sure, but from what I've heard of it, you could
theoretically play it as a combat/adventuring game without using the sex rules at all. I'm not sure why you'd want
to (or why you'd want to play it at all, for that matter), but that does seem like it might take it just barely
into not-quite-porn land—if the sex can
be omitted without ruining the game.
(Assuming a game this bad can meaningfully be called "ruined".)
Now we just need some volunteers to try to play a sex-free game of it...
"Existential Despair" is an oxymoron.
