What percent of population PMOs?

Ive been wondering how many guys (or girls) watch P or fap.

I have oftentimes heard "every guy faps" or ""99% of guys watch P so don't feel bad".. but i really don't think that's the case. Most people i see around school don't seem like they PMO.

Also, if 99% of guys PMO, then why are there only 160,000 people on nofap. Shouldn't there be a lot more?

Are there many more fappers but they just haven't joined nofap because they don't see it as a problem. Or is it because they aren't addicted?

What do you guys think?
