Initially: working at the bar and the inn. YOu can use the money to buy "Stimulant" which gives Slut++. Later on you can viist the bathouse and fool around with the guys there. Again later on, you can work in the brothel (i.e. the cave in the south west of the village).
Yeah....it freezes for me in the tavern where they masturbate the waitress....every time.
