IS ANY SEX POSITIONS BESIDE THE MISSIONARY SINFUL?

I am shocked when I hear people say that any sexual position other than missionary is sinful. I am under the impression that what goes on between a married Christian couple in the privacy of their bedroom is between them and their God.

I just think that if God created my wife for my sexual enjoyment and me for hers. Then, we are glorifying God by being faithful to one another, as well as expressing our love whatever sexual position that may be.

What is a missionary position? A position for sexual intercourse; a man and woman lie facing each other with the man on top, woman underneath; so-called because missionaries thought it the proper position for primitive people. 

In my research about the origin of the Missionary Position, I discovered it arose in response to teachings by Christian missionaries, who taught that the position was the only "proper" way to engage in sexual intercourse. In reality, the term probably originated sometime between 1945 and 1965 through a confluence of misunderstandings and misinterpretations of Bible verses.

The name comes from the days of Missionaries travelling the world to spread the word of Christ. The natives in wild and foreign places had sex in all kinds of ways and very openly. They received many lectures from the Missionaries about modesty and covering themselves and chastity. The natives didn't even know what fornication was until the Missionaries told them. The natives became curious about how and if the Missionaries had sex. When they peeked into their huts all they ever saw them doing was the "Missionary" position, hence the name.

This was during the Victorian era when things sexual were much proscribed to young couples. Sex was only for babies and not to be indulged in merely for pleasure. There was only one proper position for sex and anything else was sinful. Certainly no kissing of naughty places was allowed! Young English women were told before their wedding nights to "close your eyes and think of England" when it came time for sex. This meant that this was a horror to be endured to bring future babies into the world and perpetuate the nation. Missionary position was the only position approved and that's how it got the reputation as being not much fun.

So, judge it by yourself. Is it proper to use different sex position or practice only the missionary position?
