Hamburg (dpa) - The Germans have less and less sex. This is at least apparent from the representative study "Leisure Monitor 2019", which will be presented on Thursday. According to this, only about every second German citizen, about 52 percent, has sex at least once a month. 56 percent were five years ago, according to the investigation. "The stress in the spare time has further increased," says Prof. Ulrich Reinhardt, scientific director of the "leisure monitor". "As a result, the Germans take less and less time for sex and eroticism."
