Importance of sexs

1. Sex for Procreation
Sex is first and foremost the means by which humans reproduce, and the pleasures associated with it are designed to compel us to have children. Most major religions speak of sex as an expression of God's love and the means by which He allows people to create life. Secular people usually maintain that sex is a biochemical process that is fused into our DNA, allowing the human race to reproduce. Whatever one's individual beliefs are, propagation remains the single most-important function of sex.

2. The Strengthening of Emotional Bonds
Physical connection results in greater familiarity and comfort levels, which in turn increase our affection for each other. Sex with your partner, when undertaken as an expression of love, is one of the best ways for you to feel closer and enjoy each other's presence. It also facilitates intimacy, both in seeing each other naked (the ultimate state of physical vulnerability) and in experiencing each other in ways that only a small number of other people ever will.
3. An Enjoyable Stress Reducer
Simply put, sex is fun. It feels great, it helps you to explore interesting sides of yourself and your partner and it expresses a fundamental part of human attraction. On a more scientific level, sex stimulates the release of endorphins and bio-chemicals that help you to relax, ease your state of mind and relieve tension and stress from other sources. A healthy sex life is important to maintaining mental equilibrium, while a troubled or difficult sex life increases stress and anxiety outside the bedroom as well.
4. Understanding Gender Differences
Men and women are built fundamentally different. This influences not only your sex life but also the pressures and assumptions that society places on you and the ways in which you are expected to interact with the world. Many people have written on the "mysteries" of the opposite sex and the way men and women struggle to communicate with each other. Sex serves not only to illustrate the function of men's and women's physical form but also to lend insight into how the opposite sex approaches the world, appreciates life and views members of its gender.
