It seems to be an unusual occupation or "calling". There are many men (and women) that have no interest in true intimacy (like Puddles). However the temptation for those men (and women) to seek release in the arms of another should not be dismissed. Vowing to live a life of celibacy - stop right there. It doesn't strike me as natural or normal. It seems a recipe for disaster. jmo
It also tends to attract people who wish to be absolved of their, er, aberrant desires, such as pedophiles and other conflicted persons. They seek the "cleansing" and "forgiveness" the calling has to offer.
The only problem is, their buried issues inevitably resurface.
