If in public you are a man and you are purposely resting your head at another man’s shoulder or if you are seen walking at public places holding another man’s hand/arm, you are likely to be arrested in some Muslim countries while in the majority of the countries in the modern world people will contemptuously point fingers at you, jeering at you for being “shameless” in a perverted sort of way…
But if you are female, such behaviours are perfectly acceptable, even in an extremist Muslim country like Afghanistan…
So women are free to do all this but men, oh, you had better not attempt such “intimacy” in public…
