I couldn't handle the idea of a woman I was either dating or married to having a past on the Internet like that. Nasty as this will sound, the thrill of getting to have sex with her or seeing her naked body would be ruined if I could find evidence of either on the Internet in 10 seconds, which makes her damaged goods in my mind.
Don't be bothered by this, 99.9% of men would have an issue with this on some level, it's natural. Leave the west and go to any third world country and the 'men' who don't think this way are rare.
it hasn't triggered the collapse of Western society
I'm not saying it will trigger it, but it is a symptom of the times. The core family unit is the backbone of society, sex work, which invites promiscuity, linked with broken families is anything but that.
And most of these "sex workers" have terrible relationships with the opposite gender. The ones you may see are the popular ones, and even they have a tough time (lana rhoads, mia khalifa). Using just basic common sense, most men will be turned off by it, so who do they get in relationships with? It's with men who either never thought of them as a long term partner, or a man who's desperate and thinks he won't care (in the future he will), or a man who is so mindfucked by society that he truly believes in the lies of the zeitgiest (does not make a good partner). Keeping this in mind, and looking at opinions online (no stats for this sort of stuff), it's clear how difficult it is to have a relationship as a woman in the sex industry. Furthermore, most sex workers are hemorrhaged by mental illness, drug problems, alcoholism, etc. Not a good base to build a happy healthy family..
