at its core it’s meant to help men avoid sinful lust, which is evidently positive (and only a hedonist would disagree).

I wouldn’t consider myself a hedonist and I disagree. Men should learn to control themselves, and that doesn’t happen if they’re never exposed to things that challenge them. Repression doesn’t make things better, it makes them awkward, obsessive, and it makes discussion taboo. Which makes abuse all the more likely.
