At the age of 15 and still a virgin, Stefanie Stappenbeck starred in this movie, where she has nude and love scenes."I shot my first leading role in the movie 'Biology!' and started burning for acting. And as a woman - I got my first real kiss, funnily it's on celluloid in 'Biology!'. That's why I see this time as the most important starting point for my current life."-she says.
