In Switzerland, a typical adult female has sex with six people over the course of her life, while an average Swiss man has on average seven sexual partners.
A survey conducted in July and August 2016 by Blick and Le Matin, conducted as part of the Swiss government sponsored “Love Life, Stop AIDS” campaign, designed to promote condom use to reduce the spread of AIDS and venereal disease, showed large variances in the number of partners. Of the 29,350 survey participants, nearly 20% had had 20 or more partners, around 40%, 10 or more, while 13% had had only one.
The study, which covered all of Switzerland, showed those in French-speaking Switzerland to be more prolific than those in Switzerland’s other linguistic regions, with a combined average of 7.1 partners, compared to 6.1 among residents of German-speaking Switzerland, and 5.8 among those living in the Italian-speaking region.
In addition, city dwellers got around more than their rural counterparts. The average in big cities was 8.1, compared to 5.6 in the countryside. The city which stood out was first-placed Basel, with a median of 12.3 partners.
27% of all those in stable relationships admitted to cheating on their partner, with men (31%) cheating more than women (24%).
When questioned on condom use, 51% of men and 45% of women admitted to having had casual sex at least once without using one.
According to the Love Life website, HIV cases in Switzerland were stable in 2015, at around 500. Other diseases, such as Syphilis, rose by 7%, mainly among homosexuel men. Chlamydia cases also rose by 5% between 2014 and 2015, mainly among women. Gonorrhea was the disease showing the steepest rise. Between 2001 and 2015, the number of cases climbed more than fourfold to over 1,800.
