Sin But you can't pick and choose what you believe just because it fits in with your viewpoint.
Also as "health care provider" now retired, I find myself in agreement with most of what you say; (and I did actually graduated over four decades ago 🤣 ).
I would only disagree with the quote above. Picking and choosing what you believe because it fits your viewpoint is basically how humans are wired. Evolution has seen to that. Most of humanity does it. It may not be science (though to be honest a large proportion of the "science" carried out by scientists isn't very scientific either - witness that most journals succumb to massive amounts of confirmation bias), or the way knowledge is ascertained. If picking and choosing makes people comfortable, does no harm to others then why not.
From personal observations (which doesn't seem to contradict the literature) I know that masturbation is is pleasurable and does not cause long term harm. Even continuous masturbation while pleasurable is self limiting and loses its appeal after a while. Enforced abstinence for a period tends to increase the pleasure when the period ends whether release is via masturbation or from sex play with a partner. This is why chastity belts can be a useful sex toy that ironically increase sexual pleasure.
There are of course many ways to abstain. Chastity devices, especially when controlled by a loving partner are just one such method. What one decides to pick and choose as to why they submit to these devices, is thus irrelevant. Science be damned! 🤣
