Some doctors seem to have caught on sooner than others to the need to ejaculate frequently. About 20 years ago, I went to my doctor complaining of chronic lower back pain. The real problem was that I was overweight. However, in cosidering all possibilities, the doctor asked me how frequently I came. I thought the question rather odd, until he explained. While I don't remember all the details, he more or less said that the system is meant to be purged frequently, and that failing to do so could cause inflamation, or at least make things irritable, and contribute to lower back pain, since the same branches of the nervous system are involved. In those days, things often got "purged" twice daily, so I assured him that wasn't the problem.
