As Moxonator89 said, fighting, dating and sex have to be unlocked in the new Loyalty table. But something else I found might be a bug - the Master cannot do the Prostitution job (and has no Loyalty unlocks to allow it.)
Also, Reward with Sex does not decrease Lust anymore. The description still implies it will, so I think that's also a bug.
Seriously, at the beginning it feels like you've got nothing you can have your slaves do beyond one fishing unless you send them to another village, and if you do that you can't train them. It takes 2-3 days of training to start to unlock Prostitution or any advanced sex training. But until you start upgrading your mansion there's very little the slaves can do while you train them up.
