We want sex, because our bodies want sex. Our bodies want sex because it feels good.
The only caveat I'd add there is that the primary reason why it feels good in the first place is because it is a way of ensuring that reproduction takes place.
"Men did not love Rome because she was great. She was great because they had loved her." -- G.K. Chesterton
I don't believe that there is an instinct to procreate. Rather, it feels good and we are inclined to pursue things that bring us pleasure so we do it. Pregnancy is one of many potential outcomes.
