A question

Hi, I have the experience where after playing with yourself, spanking the monkey I feel really pent up and low energy and physically tired. I can't figure out if this is just "blue balls," as they say, or whether it's from my endometriosis. It usually lasts about 1-2 days afterward, and 2 nights of sleep tend to make it dissipate. It seems to happen whether I come or not, but might not an orgasm be incomplete if one does not have a transcendent emotional state along with it? I'm thinking that this could possibly cause the "blue balls" I referred to, if that is indeed the cause. Maybe what I'm really asking for is a definition of "blue balls." I would like to be able to differentiate that from symptoms of endometriosis.
Thanks. Tweet
