Pornography is wholesale prostitution. Where did you learn that all prostitution culminates in sex with the physically present female or male? ... Your argument sounds vaguely familiar, similar to the one Jimmy Swaggert tried, to exhonorate himself for hiring prostitutes but he didn’t have physical sex with them. Your perspective is vaguely like sinkEmperor clintoon’s, telling the world his oral sex with Monica was not sex. But nice rationalization for your desired behavior.
Webster disagrees with you. Using bad analogies multiple times doesnt make them more true.
