Horrible Person. Besides being illegal, it's also extremely dangerous not to mention he's teaching his son some very warped hyper-macho values. Of course that wouldn't be as much of a problem if brothels were legal and regulated but still.
What's hyper-macho about buying time with a prostitute?
Not so much the act as the idea of someone thinking they can make their son a 'man' by having him f**k someone (or several people) that literally mean nothing other than what you paid for them.
Now obviously, I don't care if people have casual sex and have done things with people I was not dating. But I find the mentality here to be repulsive. That and this is incredibly stupid.
