Alright, I'm taking a shot with the same disclaimer as Coppertop...

You say you've turned to mastubation a lot lately... Masturbation, or rather, orgasm, releases endorphins, hormones that bind to opiate receptors in the brain. When you have a lot of build up of any chemical in your brain, it creates more receptors, and that same amount of a chemical does not cause the same rush it used to. (This is, if you haven't already seen it, the backing to a lot of addiction problems)

What this means is that, while the orgasm still causes a surge of endorphins, and thus the characteristic opiate effect, the magnitude of the effect is lessened. What's more, the level of endorphins your body releases throughout the natural course of the day may now only have a negligable effect due to an intense increase in receptors. This could result in the depression you seem to feel since your brain is becoming accustomed to having a much larger amount of endorphins... like a kind of pleasure withdrawl.

Please, some medical person correct me on this and tell me I didn't actually just correctly analyze why masturbation could lead to depression... It seems like such an uncharacteristic thing for me to do... (being right, that is)
