This is a good study and I welcome it, I have always held that a good "flushing out" is good for men (and boys). I do still believe that morality and following a morale standard is important. But I have always felt that the WT goes beyond itself with medical advice, look back at all the quack medicine it promoted.
On masturbation (self abuse WT speak) it does not lead to Homosexuality (see youth book) nor make you blind. It does not make you neither a sexual pervert nor does it make you more of a sexual person, we are naturally sexual, and have the desire to be sexual, this is very normal. What I support is to get to know what your own feelings are and really understand yourself. Maybe sexual perverts masturbate excessively or not I don't know. What we can do as individuals is to know what is right and wrong sexually (who sets the standard?).
Being a Jehovah's Witness for many years up till now I had many guilt feelings along with worthlessness and being undeserving of Gods kindness (grace) everything being either wrong or right being told what is best and what is not good or to be avoided. Now that I have grown up (as free thinker) I look at everything with a critical view and decide whether or not to accept it or reject it on my own intelligence. I now no longer feel guilt about anything at all, maybe I feel remorseful or take the view of "well I did that but I was wrong" and move on.
I look forward to the WT's reporting of this medical theory!
Maybe Prostate cancer needs more attention as too many men are suffering and dying from this dreadful illness, I say look after your Prostate.
