Re: desperatly confused newly wed
He seems open-minded enough. Maybe sit him down and have a sex-talk with him. Go over what you like, what you don’t like. And you have to be specific to him. If the sex gives you too much pain, then maybe you both need to seek some medical help. There are lubricants and such you can use.
If its his cleanliness, then talk to him. He should be fully showered before coming to bed, and perfumed. Give him a talc for Eid. 
If he’s ridiculously hairy, then sugget waxing to him. Paki guys are not that open about it, but seriously, after some guys do it, they LOVE it.
Or turn the lights off.
This is a tough situation, and I know lots of people are saying you should have thought about this…but Pakistanis typically don’t have sex before marriage to try things out, and a lot of times women find that they’re ok about the marriage until he takes his clothes off.
You also have to ask yourself - are you repulsed by HIM or the sex act itself? Some girls just really do not like sex at all. Or maybe, you need to explore the sexual inner tiger in yourself?
And by the way, I hope you know that some guys do not last 5 minutes. 5 minutes is DREAM to them. And their respective wives.
