Im curious about views in gulf, is it kind of a viscious circle, women aren't supposed to sexualise themselves, and will pretty much be virgins/inexperienced but the guys will have some experience. They will then see their wife as 'boring' or bad at sex and then cheat/hookers etc

In the west it can be for both reasons and depends on the individual, either partner could be feeling they aren't getting enough attention, and when another person shows them they are so desperate and lonely they will take any attention. It is generally thought that men see sex as physical and women more emotional. But as atitudes changes you are also seeing women who just want sex for fun too.

Unfortunalty like many countries -
*)man who has many partners = stud,manly, masculine
*)woman who has many partners = slut/skank

You rarely hear men called sluts.
