Just out of curiosity I had a look at this post to see what you guys actually think. I am a Christian not a Muslum. I will share with you want our God thinks about issues like this.
Firstly we agree marriage is the only place for sex. Note the following verese from the bible:
Marriage should be honored by all, and the marriage bed kept pure, for God will judge the adulterer and all the sexually immoral. - Heb 13:4
There seems to be a lot of confusion here about, what is permissable and what is not. In my opinion based upon my knowledge of God I say all things are permissable if they are done in love, i.e. both members ofr the couple are willing, i.e. not under compulsion. Love is to consider the other one, to show kindness to each other. The bible is full of verses asking husbands to cherish their wives, and for wives to respect their husbands. Coming back to what is permissable note the verse from the bible below:
So whatever you believe about these things keep between yourself and God. Blessed is the man who does not condemn himself by what he approves. - Rom 14:22
Christianity is not about rules it is about freedom, freedom from fear, the devil would have us fear all sorts of things, and make every thing difficult to do. The devil makes us think that if we don't do x, y and y God will hate us. But in reality God is a very good God. He gives freedom to his people to make choices.
Obviously you can't, murder, steal, take revenge, harm others; becasue God is love, he is compassion, he is gentleness. He does not care what we do in all the other areas of life as long as we are showing love to people. I mean seeing this is about sex, I don't let my wife do oral sex to me just becasue I feel it is degrading, unclean, but if she wanted to I would not say you can't, the bible says the wife has the power over the husbands body to do with it as she pleases, and like wise the husband over the wife, i.e. they are not to deprive one another of sex. Some people do that, punish others by refusing them sex, but God is loving, and does not want us punishing one another, but rather getting rid of all bad attitudes toward our partners, by allowing his nature of complete forgiveness to be worked with in us.
