Well, Saudis have not one but two solutions to this. Remember the equilibrium between freedom and safety?one of them gets blind drunk and is taken home, where the other takes advantage.
All of these increase the likelihood of consensual sex. Funny enough, false accusations fit the modern idea of rape. Now, it's not the statistical truth, but this stuff is always case-by-case so either the accusation is false or it isn't.Lots of "normal" people when hearing about a rape will find it doesn't fit their idea of rape and thus doesn't count. They had consensual sex in the past, the victim consented to some stuff, the rapist took the victim out to dinner and was owed sex, they were married etc.
