>speaking frankly i think porn does do a lot of harm
What harm does it even do? The most convincing thing I heard is that it decreases productive use of time, but even then I've probably wasted more time watching random youtube videos I'll never remember than masturbating. At least when I spend the entire day reading eromanga I'm engaging with a prominent part of a subculture I'm passionate about, so I'd say it's still more productive than other time wasters.
