That's the thing, how would a man be able to meet a brand new woman every single week, two weeks or even a month? This could be on tinder, the gym, class, grocery store or anything you could imagine. Now, out of all of these women how many would he be able to get out on a first date, meetup, hang out or whatever? Now, from here how many can he potentially have a one night stand with, first date sex etc.? If that doesn't happen, how many of these first dates/meetups would follow through on a 2nd date? Then from there how many would he be having sex with?
This would take a ton of time and energy, even if you did invest both of these variables there'd still be no real guarantee that this would ever happen lol.
