OK, so, to be honest ALTHOUGH that would really, really bother me in a way that normal porn doesn't, if he is spending that much there may be a chance that he has an actual problem, and could use help rather than being yelled at. Maybe just talk to him very calmly about it to see if he feels like it's an addiction? This sounds silly but guys can actually become addicted to porn. I dunno, it just strikes me that it may be that rather than just a normal, healthy ****-sesh because it's basically the next level down from going to an actual prostitute...
