To accompany Muriel Wimmer (Sarah) and Antonia Putiloff (Charly) during the shooting, the director Christian Klandt and his film team were supported by two sex education specialists from pro familia Berlin. For the 16 and 17 year old actresses, sex scenes in front of the camera were completely new territory. The experts were on the set for all the sexual performances to accompany, advise and support them. However, pro familia Berlin only gave its approval after reading the script and after preliminary discussions with the filmmakers and actresses. "It was very important to us to compare the content and messages of the film with the stance of pro familia. Is it safe that young people are not exposed, defamed and stereotyped? That the negative image of pornographic youth is avoided?" says sex educator and counselor Petra Winkler. On the set, they were always approachable for the young actresses, with whom they had built up a good level of trust in the run-up to the shoot. "We were not governesses," says Winkler. "The girls weren't forced to play in the film, they wanted to be part of it. Still, nudity, sex and intimacy in front of the camera were new and sometimes borderline. "In one scene, one actress was so insecure that she stopped shooting," the pro familia expert describes a situation. "It helped her that I was there as an outsider to bring calm into the scene and could talk to her."
