Can Your Brain Run out of Endomorphins?

Suppose you were able to prolong orgasm for several hours (using yoga/tantric techniques). Would your brain run out of endomorphins? How much of this stuff can your brain manufacture?
What do yoga masters have to say aout this? Sting claims to be able to maintain orgasm fr 6 hours-is this possible? Is it desireable?:rolleyes:

AH, you mean endorphins. Endomorphins is a made-up word, I believe, unless you are referring to the endomorph body type. Which is kind of funny if you try to plug it into your post.
