The way I see it, in a perfect world, people would not have to feel ashamed of their bodies or the very natural physical aspects of love. And for a long time (and in some places still) people felt that way, until some religions screwed things up.

I don't see how that has anything to do with christians teaching of wanting people to be married before having sex.
Ah, but they are not saying you should be married before having sex. They are saying you should best not have sex at all, and that is the problem.
