The most points you could get by doing a "Lost Acolyte" quest and picking the most naughty options. It was raising lust for acolytes and in one situation also the warriors lust. Otherwise those are some situation - there's one talk with Rhot where you can give him lust potion, one situation with acolyte in the ruins where you can give her lust potion. You can get some points when offering a relief to warriors (only between 22 at 2)
