Your "private spot" contains many nerve endings that when stimulated, encourage chemical secretions in your brain that create sensations that are considered pleasurable. Some chemicals secreted include oxytocin, endorphins, adrenaline (epinephrine), phenylethylamine, testosterone (both men and women) and serotonin.

In short, you rub your private spot because it feels good.
