You don't!! And as a warning be very careful here as many Sheriffs depts. Are running undercover stings to expose those who solicit prostitutes on the internet. But it's your choice but won't get any numbers on the internet as they don't want harassing calls.
Prostitution is illegal in many countries around the world, and therefore you should not try to pay people for sex without knowing the rules of the country.
Personally, I think that prostitution is an awful thing, regardless of the laws in a particular country. You're highly unlikely to be able to find a prostitute's phone number on the internet for several reasons, including the following:
- As mentioned above, prostitution is illegal in a lot of countries. Authorities keep a keen eye on any potential illegal activities on the internet, and would likely shut down any chance of people obtaining contact details for prostitutes.
- Some authorities may try to catch people looking for prostitutes by posting a fake phone number. If you contact this number and arrange to meet, you'll likely be arrested.
- There are likely many people pretending to be prostitutes in order to have a laugh at the expense of those who call. Have you ever read those terrible wall scribbles inside public toilet cubicles? "Call this number for sex". Yeah, that's pretty much guaranteed to be a joke at the expense of the caller.
Ultimately, prostitution is immoral. The whole process devalues and objectifies women, and that's wrong, in my opinion. I'd suggest that you stop looking for prostitutes, and try to develop a genuine relationship with someone.
