I subscribe to the school of philosophy taught by the doctor on Hee Haw.
"Doc when I do this (rotates shoulder clockwise) It hurts."
"If it hurts, don't do it."
I've never tried some of those things y'all are talking about, but I have heard they hurt. So I'm not going to do them.
Sometimes the stuff that doctors do to their patients is painful- and most people understand the doctor is not trying to actually cause harm or injury.
There is stimulating pain; and pain from injury. Obviously anything causing injury is probably bad- but some people with psychomotor issues (mind-muscle connection) would prefer a bit of pain to re-establish that connection over feeling numb or weak.
Of course, there are people that would never be persuaded that deriving anything other than feelings of horror from pain-stimulation is demonically inspired.... but as sombody that absolutely loathes biology-nerdism; I think we have to appeal to biology on this topic in particular; not only because it's testable in real-time, unlike macroevolution et al. bio-theories used to defy God and exploit people with "science"- and it's such a niche-topic that it's not even addressed in scripture, as far as I know.
OP's
overall topic isn't even really addressed by scripture- the implication being, IMO, that we either need to pray for an answer, pray and look for an answer, or we actually don't even need the answer, even if we want one.
I could see somebody that intends on or has marriage prospects wanting to sort this out- in which case... talk to your prospect and talk to God.
Even when I have heard pastors, et. al. try to even tangentally address OP's topic, it has always been a feeble attempt, imo, to address a hypothetical "expectation of men, caused by pornography"... but even that fails to comprehend that
pornography did not create itself to influence men... it is a product derived from the desires of the flesh that are inherent in both men and women to begin with.
So many of these problems that married-types are having would probably not even exist, if they actually bothered to TALK to each other before they got married.
