You can get the masochist trait if you get involved in certain scenes for enough times. The fastest one is a scene in the VIP area of the Queen of Hearts (a guest there can "teach" you a thing or two). There is currently only one way to get the pass: when you work as a bodyguard during a quest for the adventurers guild, you can find a tiger a noble keeps as a pet. Distracting it with some food will let you pick up the pass. There will be another way in version 0.976 (you'll be able to get the pass at the model job, as long as you are past chapter 1)
The other way is getting spanked at the secretary job (but that is slow, and hard to grind). I need to add more scenes which raise the stat, but for now that's it. The hypnosis is much faster! XD
For the bimbo trait, you must get involved with Sonya, the owner of the Queen of Hearts, but you must not have marintas charm with you, or you start her alternative path and won't get the trait. Again, I should probably add more ways to get the trait, but this is it.
There is no "bisexual" trait, being worried about your sexuality with the hypnotist just gives you the titty lover trait (since the protagonist is already bisexual XD).

Really happy to hear you like it this much! ^_^
I used to do this as a hobby, and my previous games were all completely free. Needing the money, I opened up the Patreon, and luckily things worked out well. It would have felt weird to try and lock the game completely behind a paywall, so I decided to use the current system. Plus, I feel like on the internet it's better to rely on the goodwill of others, since everyone could pirate the game, if they wanted to.
I hope you'll get your job back soon, whether you become my patron or not! :)
