That first sentence gives it away: you'd "like" to "think" you're "progressive" as you are "well aware" of women prostituting themselves. Progress and moral decay are the same thing, the real problem is you liking it and equating it with thinking.
Your third sentence reinforces this, and offers another strange conflation that you "can't complain" which is "okay". Sounds like you're saying that it's okay that you can't see any issue, which would only be okay if there was no issue.
But there is an issue, and that's the parasexual, parasocial behaviour of women showing their tits for attention while you beat off like a captive chimp. It violates a basic understanding of how we relate to one another, and the kinds of relationships we can expect to have. That's the first harm.
The whole, btw, fucking point of society is to keep forming and reforming itself. Families are the ways that it does this. You may have noticed that sex makes babies, and that babies are defenseless idiots. They need two parents. Those parents have to be a man and a woman, and that man and woman need to keep cooperating in helping that baby for years. They can't do that if they're incapable of forming deep bonds because they'd rather just trade money and attention for sex.
Maybe you, thinking yourself a progressive, like this. If you come from a broken home I assume it's because you've never known real love from your parents (sad, many such cases) , and if you come from a functioning one you probably take it for granted that you have an integrated personality and can move confidently through the world, doing things like sharing your dumbass takes without even worrying that you're wrong about everything.
