KS. yes I agree, most religions have codes for controlling sexual desires, however, point is, even from the bibles view, that this is done in order to prevent damage to others or one self (e.g. sexual transmitted deseases, broken marriages, abuse or even rapping)
when it comes to masturbation, its something virtually everybody growing up does, it does not harm neither one self nor anybody else (normally, perverted people is a different story) however, with strict rules like in JW, poeple feel guilty and unworthy.
Intended or not, but feeling of guilt will urge poeple to compensate with more field service, donations or whatever...
I agree, sexual desires in a civilzed world need to be controlled, but not condemned like the org does...
