That is true, but some people will still have the desire to be viewed in a sexual manner or observed having sex without capitalism. It existed before capitalism. Some people enjoy showing off their body in varying ways, from a little sexual to extremely sexual, just because they like it. There is nothing inherent to the capitalist mode of production here.

I agree with you on most internet porn though, people are addicted and watch way too much of that stuff. And have really weird libertarian style reactions towards anyone critical of it. Remember that user, who turned out was trying to solicit users though direct messages, throwing a massive temper tantrum when Pornhub removed unverified videos?
