It wouldn't surprise me if top users are going through three+ partners per day.

A post-wall divorcee managed 10 matches to assign them to 10 days, almost instantly on Tinder -- all of whom were willing to do the deed: https://observer.com/2017/04/ten-tinder-dates-in-ten-days/

To her credit, she didn't go through with it, but to your point, if she wanted to she had 10 easy-made matches assigned for a week-and-a-half of disease-catching/spreading.

Just imagine what the slatterns in their youth are doing and the bodycounts they're racking up?
