DAILYMAIL.CO.UK - Feb 4 - Research of 30K single people in the UK, US, Canada and Germany, has found that ~59% of daters are willing to have sex on the first date. German men and Canadian women are the most open-minded. Dating app Jaumo - which was founded in 2011 by Jens Kammerer and Benjamin Roth - also asked their users if they would be open to having unprotected sex outside of a relationship, and surprisingly people were open to it, despite the risk.
