Sex Up - Jungs haben's auch nicht leicht (2003)

In Sex Up - Jungs haben’s auch nicht leicht (2003), three teenage boys grapple with the usual teen issues--that is, sex, sex, and more sex. Their main problem is that none of them can get laid to save their own life, though that doesn’t seem like much of a problem compared to the boy who farts whenever he approaches an available young lady. All of this changes, however, when one of their parents returns from holiday, bringing with them a mysterious plant that makes you unbelievably horny when you drink the juice from its stem. This is a fun, intelligent sex romp à la American Pie (1999). Sabine Kaack is hard to see behind the shower door, but you can make out the briefest of boobies.
