What possible other motives could there be for meeting a random man for sex after seeing nothing but his shirtless pic online? Or grabbing a man in a club where it is too loud to even speak and taking him to the bathroom?
I used to do it when younger and some girls wouldn't want you to even know their real name. There is a large number of women who obviously want purely physical encounters with no other intention.
Sure, 99% of women maintain the search for “Prince Charming” but these physical encounters are not part of that goal. They are purely for fun and sexual release between any serious long-term dates.
