Why do so many of these men on dating apps bring up back scratching?

I went on a first date with a guy and he Grabbed my foot and licked my toe at a restaurant. My girlfriend's happened to be eating across from us and saw the whole thing. Right away one of them messaged me that I had an emergency at home so I could get out of the date. She saw the look on my face. I know people like doing that and I know there is something to it ( LADIES give it a try at least once if you are comfortable with it. And make sure they are a "seasoned " player 😎) I think it should be something more private for the first time,
. make sure they get comfortable with it Wait a minute.. Not in the first half hour please .
