Having too much sex will make you unhappier in the long run.
Your desires will increase (which leads to distress) and you will need more of it to feel less of a feeling of "well being". Not to mention that you will end up being controlled by it, which has many bad consequences, among them that you will do shit that will later regret.
If you prefer a more "scientific" explanation, psychologically, addiction to sex is not unlike addiction to drugs, alcohol, gambling, etc. If you look at recent research, it works in the same way in the brain with the dopamine rushes and all that. One interesting thing about it is how having too much sex works with drug addiction. Since they affect the same brain chemicals, having too much sex makes you more likely to develop drug addictions.
