The following is my personal opinion, please do not read if you are against prostitution.
It's sad that many people, even in today's society, think that paying for sex is immoral, or a bad thing.
If an ADULT woman (or a man) is willingly selling that particular service, there is no reason for any of us to stigmatize, discriminate, or hate.
It is a choice. And it deserves respect. Whether you like it, or not.
