It can be summed up with, "If I want you to touch me I will let you know. Until then please keep your hands to yourself."
I think they used to teach that in kindergarten.
Not true.
I've dated a lot in the past. When I made my first "move" I rarely had any indications that the "move" was desired. Funny, it is a crap shoot. I was never rebuffed very often but I sure was in doubt as to the outcome every time. On the occasion I receive the push back my standard reply was "Just checking".
So ladies what is this mythical universal subtle signal? The left pinky raises in excitement signaling it is a "go" for the advance?
Men are risk takers and learn to take rejection early. It is almost a rite of passage to be rebuffed a few times.
Women in general are afraid to send that signal out for fear of rejection.
“Hands to yourself!” is Rule 2 in my house and Cub Scout Pack. (All the leaders now shout, “Rule 2!” to the amusement of outsiders.) It used to be Rule 1, until I decided, “Flush the toilet!” needed to be Rule 1.
