The real issue with men picking up women isn't that it could be recorded, it's that women really treat the men so hostile that the guys eventually get turned off from ever doing it.

It's basically a shock collar effect. Every time a man tries to pickup a woman he's barking and the women immediately shock the man with a shock collar. Done enough times the man stops barking.

If women want men to approach them more then women need to reward men who approach them.
