If you never learned how, wear the cum tank shirt from the Cum Lovers Club (if you haven't been there, follow the questline from Annie in the mixed baths) and then just get fucked, preferably in the pussy, and afterwards you get the vial of cum, though you may need to have vials on you.
put a negative symbol in front of the 9's (both sets of them). That's what I did and it made her more submissive, but you want the attitudes to be positive 9's, makes her more willing to do stuff and the kink is sub or dom.
