Scharf wie Chili (2005)

The attractive student Tino Köster enjoys his many promiscuous affairs. When he sleeps with his brother Stefan’s bride, Esther, at their wedding and his family disowns him, Tino joins the “Anonymous Sex Addicts” self-help group. There he unexpectedly encounters Esther, who has similar difficulties with her sex life. After the members collectively achieve their group goal of 90 days without sex, they realize that their problem is not actually too much intercourse, but a lack of love, acceptance, and true friendship. Tino and Esther fall in love and marry, but only after Stefan has once again unsuccessfully asked Esther to marry him at the altar.
