So you didn't understand the video? I thought it was pretty straightforward. 

And if it's such a great harmless way of making a living, why aren't men doing it? 

How do prostitution and pornography HELP women OR men? You'd have to be a complete fool to imagine that anyone goes willingly into these forms of work. It's essentially paid rape. 100% of those in the sex trade were abused as children. Try and see the WHOLE picture not just what MGTOW tells you. 

Also eventually men stop being able to get a hardon at all when they use these immoral means of sex. And of course, prostitutes do not get turned on at all by sex whether paid or otherwise after doing this long enough.
