I mean, yeah, that's the only M/M content in the game, but there are a looooot more M/F and F/F content.Most M/M scenes in carnal instinct are with random NPCs walking around as part of the dynamic sex system. As for the wiki, it's not entirely up to date, accurate, or in full detail. For example,You must be registered to see the links(Specifically "Stockades") is for male players only, and you can pick a female or male NPC as the recipient. Similarly,You must be registered to see the linksalso features a M/M encounter.
Male characters get the short end of the stick so far. Waaaay less forms for male characters, possible sex scenes, sex partners and even equipment! It's silly that there is only one set of male clothes that is common and overstated because there's nothing else to use out there.
Edit: Hopefully this will change soon, as they are adding new male skins to jackal, even a male exclusive one (for now)
