I briefly played this game a few years ago. I stopped when the game forced me to have sex with a gross bum in the street because I had the exhibitionist trait/status/passive/whatever which made no sense. Is that how the game still is in general when it comes to allowing the player to choose what to engage with?
it is a wile sins i last played this game, but i seem to remember you only got forced to do something like that if you Failed the Merchant Quest and got a "Cursed Amulet" Forced on you.
the "Cursed Amulet" that wold put you in a suggestible state when hearing certain Keywords, think is ware something like "Big Tits" or something, and if a random stranger say it and then ask you to go whit them, well the "Cursed Amulet" will do the rest...
basically it is a punishment fore getting caught in the quest.
(think you can also get an Debug version of the amulet in the Debug Room, that exist to test events related to the Cursed Amulet.)
only other think i can remember is maybe being drunk whit low inhibition (and lowered Willpower) isn't known to make people do rational decisions...
so to try and not be forced into situations like that, try and have a High "Will" Stat (the stat that let's you do your own decisions over having other decide fore you.) and don't get Cursed Mind Affecting item's put on you.
hope this help's a bit, and have an hopefully good gaming experience.
