Worldly view of sex is that there is nothing special about it despite the hormones and pheromones involved.
Some pseudo religious views confuse hormones and pheromones with spirituality. Once those die, their spirituality in sex dies as well...
The biblical view is not to say that sex is not fun or very enjoyable. But it makes sure to emphasize that it is a very spiritual experience that should only take part between husband and wife.
The world also puts sex before marriage, with the common thought being "what if I marry and the sex is horrible, I should know first".
God puts marriage before sex, while sex is great it is not the foundation for marriage, but more so it's like salt and pepper on an amazing steak.
The husband and wife have different roles but are both modeled after the same person: Christ.
The husband leads the family in the direction they should go. But while doing so, he should not be overbearing, he must put their needs above his own at all times. Love them more than himself. Just as Christ loves the church.
The wife directs the children in the way they should go, she follows the husband as Christ follows God. This does not mean she is to be seen and never heard. She is vital in the husbands spiritual growth in Christ. A good mother can mold a family like no other. Same with a father. But it is a duality, neither can do it alone, both are co-dependent.
