Is it normal that i want to experience ass play, afraid it might hurt

I would suggest you start with a small vibrator or a butt plug. Buy some lubricant. May sure you have emptied your bowels and your arse is clean. Was your toy when you have finished and hide it away.

It hurts but for about 5 minutes and it's not very painful, just slight pain to acknowledge that something is there. After that it feels great and you will even ejaculate without touching yourself. Go for it

I think anything going into your ass is not normal and borderline gay, even if you are sodomizing a woman.

If she is reserved sexually, you probably won't be getting that kind of action from her. Her sexual limits is something you should have talked about before getting married.

Another good reason for sex before marriage. Visit one of those looser massage parlors. They'll probably do it for a fee. Or you can buy your own toy.
