Bets are not finalized, and some options might be missing. This is because I'm working on a new addition to the bets list, which you'll see in one of next week's updates. Also, your sissies will be able to automatically agree to have sex w/o condom.
Multiple bets selection is 100% works for 'Agrees to be your sissy' + 'Agrees to have sex with you' combination. Does that work for you?
You can't make them accept an idea through bets, though. You can make them agree to certain things. I know what you mean, though. If you make them agree to be castrated or start HRT by winning a bet, ideas ('You don't need your balls anymore' and 'You should start HRT') shouldn't be in the brainwash list. That makes sense, but the brainwashing system is not yet finalized, there's a lot of changes will be made to that.
Thanks!
