I don’t need a long explanation. Prostitution is illegal. Porn is basically the same thing: selling sex. Why is one illegal and the other not?
Because you aren’t an active participant doing quid pro quo.
Personally it shouldn’t be illegal. I’d never use it because of disease and I don’t believe one shoyld pay for it. One of the reasons I advise afainst marrying modern women today, its quid pro quo and believe me, you’re paying for it. And then less and less of it, until you are still paying but getting nothing.
