Those articles were written by the people affected by post-orgasmic illness syndrome - just compare those symptoms from them with ones described by POISers lolThere are a large number of books and medical articles on masturbation, written before the sexual revolution of the 60s when masturbation was still considered unhealthy. But they don't pop up so easily in search results. They were written in the early 1900s, some in 1800s and a few of them even 1700s, without going into the ancient writings on the subject. Some of them may have bits of religious dogma, but the large majority are based on empirical hard evidence, not on theory like the modern propaganda. The coomer's only arguments are "serotonin = good, endorphins = good, oxytocin = good, therefore masturbation = good". I haven't seen anything else in favor, so far.
Which symptoms do you have after orgasming/ejaculating?
