I am referring to these equestrian 3 and anal addict 3
Equestrian happens as you're anally raped by Centaurs by, presenting you ass while they're erect, losing, or going to camp and manual-failing the 'not slutty enough' check. Anal Addict just increases as your ass-fucked, grabbing catamite and going to the brothel is your easiest way, and gets you gold for it, quick note, do it with hunger charm for the least food drain. or you use the Warlock's curse to make it 3, I think ass has the worst after-curse repeatable event though.
Can anyone tell me how the options you get in the Manor with the magician affect the game?
Ass/Mouth don't, they just increase the Anal Addict/Oral Addict levels to 3, with a bad-end occurring if you're already at Anal 3. 'Girl' will make you unable to get hard, or ever fuck anyone, except while conveniently being inside of a sex-scene and getting ass-fucked where the art doesn't have to be altered.
Speaking of Warlock, it was working fine, you could read the diary then surrender after, but it seems they changed the diary conditions while trying to fix it. You still have to be Brothel Quest's 3rd part before fighting the Warlock, but you have to go back inside after to find the Diary again, which blocks the repeatable events for it, but you can return later after the quest to do them. Ideally the diary would block the repeatable after starting the quest, and not require you to time it like this.
