There might be SOME marriages here where both people feel comfy getting their freak on with one another, but by and large, it's the attitude that your wife is special, like a rare jewel, and so you only do proper things with her.
Hell, even if they wanted to, they're not allowed (religiously) to engage in any back door action (reminds me of how in the south, sodomy and oral sex were/are against the law in some US States).

I think it IS becoming more common here that females have more experience than they did before, so it's no longer just the men that are trying things out beforehand (though that is still the norm for the vast majority of women, I think).

I hope it starts becoming more par for the course here that young couples present their partner with a certificate that they are free from STDs before the marriage. God knows, the men here seem to have no problems paying for sex (personally, I find that amusing...if I were a man, I would be embarrased to say I had to pay to find someone who would f**k me), and with all the bi stuff that occurs here, I wouldn't trust my fiance to NOT have some STD on our wedding night.
