Doesn’t the Catechism understand pornography as removing the sexual act from the context of marital intimacy? Posing to arouse is already a sexual act, even if it’s not intercourse.
Don’t forget it’s so horribly demeaning. The objectification is no less of a problem than the boiling blood, I think. Any stripper show is demeaning. That’s one of the aspects of nudity throughout the Bible, actually - the fact that stripping people of their garments strips them of their dignity. Strippers don’t merely cause lust by showing what they have. They provide gratification by abdicating their dignity. Some people get off on someone else’s humiliating himself. Also, sex is the most intimate thing. Men who buy sex think they owe the woman totally since for their cash (instrument of authority) they get her to have sex with them, show them her naked body or perform some act. There’s not much reason to suppose it works differently in case of male strippers performing for female audiences.
Ponder this. If viewing the naked form of a woman was sin, then Adam would have been the first sinner, and not for eating the wrong fruit. I know this is not a complete comparison, so I am going to broaden the question. Is looking at a naked woman that is not your wife a sin? My feelings on this are that as long as you do so without lust, then not at all. If seeing naked women cause you to lust, then do not go around looking at naked women, because then you are sinning.
