I think there's a level at which masturbating and looking at porn becomes unhealthy, but there has to be a better way to address that.

Unfortunately, discourse on where that actually begins has been so thoroughly and completely poisoned by religious groups that are only using it as a recruiting opportunity, as well as nominally secular groups like this which are also effectively used as a recruiting ground for reactionaries, apparently to a degree more similar to incels than I previously thought. Arguably, the better move is to not give these groups an inch, because arguably most places in the world tend to have pretty reactionary views on sexuality and people are generally going to have a low estimate of when this becomes a problem, which then makes them prime targets for these groups. There are also studies finding that self-reporting for porn addiction is a much more reliable indicator of religiosity than it is an indicator for porn consumption, which should pretty plainly show that the actual effect of this rhetoric is that people who aren't really doing anything unhealthy end up manipulated into a cycle of self-hatred and shame far more often than it actually helps someone who actually has a problem.
