We are programmed to have and want a lot of sex, because...you know...children. Purpose of evolution is to multiply yourself as much as possible. Like Soleron already said, the feeling after is a reward just after using drugs.
There are also other things we enjoy like hobbies (painting, gaming, skating etc). And I think those are necessary to attract other individuals of the opposite sex because of the many variations in our genomes. Eventually sex is the most important.
