I would never date a person who had purchased the services of a prostitute (especially a street prostitute) although someone who has dated a prostitute or former prostitute would not eliminate someone from my dating pool.
(Quick caveat, this applies to North American street, and escort service prostitution - I do not know what things are like in Europe or Asia)
When I was a teenager, I was a street kid, I have known and been friends with many prostitutes and many times I saw the temptation and coercion to pull a trick.
The biggest reason I am against prostitution is many street prostitutes are children, although they don’t look like it.
I have known girls as young as 12, who although they looked much older than Jodi Foster in Taxi were no less of children, damaged, abused children, being forced by poverty, hunger, pimps, and what not who were selling their bodies. I have seen the extended damage it does to these girls and their personalities, their souls, and their lives.
I have known 16 year old girls who were on cocaine and heroin, provided by the pimp to keep them in line. I have known girls who were kidnapped by pimps and forced into the trade.
I knew a girl who used to work the streets in order for both her 11 year old sister and her to have a place to sleep at night, and she was murdered almost 20 years ago.
I knew a 14 year old girl who had a miscarriage, and the next night was sent out to work.
I had taken girls I knew on hitchhiking trips to get them away from pimps who wanted them, or just to get them out of the job and in a new city.
Although young girls are the majority of prostitutes, I have also known boys, men, and adult women who were selling themselves.
I have known teenage boys who sold themselves to eat, I have known 14 year old transvestites, and 20 year old transsexuals who have no other way to make money.
I have known 20 and 30 something year old escorts who had their children taken away and plunged deeper into addiction, and even death. I had more than one friend who’s mother was an escort as well, and these children of the escorts, are often messed up too.
I have never met the happy hooker who did it because they just loved sex, although some were good at pretending, and even said those EXACT words. I knew these people as friends, I knew the life they had lived, I knew the truth behind the facade. Every single one of these people I met were damaged beyond the pale.
Because of what I have seen, I see the patrons of prostitutes as perpetuating and adding to the abuse these people already have lived without regard for anything but using another humans body to get off instead of using their hand. Any person who would not have enough regard for other humans to consider the age and emotional condition and is only concerned with achieving physical pleasure with another human being is not the type of person I could respect, never mind date.
