Middle Easterners would consider a son going against his father perverse, particularly a King's son and heir. Jonathan in effect is giving up his throne as crown prince. Saul wife doesn't want to be bothered with a husband out farting around with idols and their ceremonies involving temple hos; ancient STDs and such.
The kissing and whatnot is a normal male thing throughout Africa, the Mediterranean, Eastern Europe, SE Asia, and the Middle East.
Only societies with sexually repressed males find it odd. They also find nudity odd, so. Ie. Don't get around Italian men or Jewish men, they greet each other with kisses and hugs. (Not handshakes which I can understand, considering)
