OK, here's this is how you might want to look at it if you're a man:
Expense: When you factor in the cost of your time, hiring a hooker is much less expensive. The hours upon hours of total bullshit you have to put in trying to meet someone on AM is staggering, especially when you factor in the catfishers and fakes.
Attractiveness: You can hire some damn sexy women and find exactly the type of woman you lust after. As for AM, well let's not sugar coat things: that's probably not going to happen. If you work hard at it, and if you lower your standards enough, then you might find someone who is "suitable" as far as looks go.
Connection. For a lot of people, it's not even about the sex as much as it is about finding someone who appreciates you for who you are. You want to find someone who "wants" you. You MIGHT find that on AM, but you're never going to find that with a hooker. Hookers don't want you, they want your money.
Bottom line: if you just want sex, then hookers are (by far) you're best choice. If you want to be "wanted", then hookers are a waste of time.
