There's a difference between a high priced call girl/ porn star / escort and a street hooker working for a crackhead pimp.
Every escort I've ever paid insisted on a condom. I can tell you that the higher priced players that hire a porn star girl will many times ask if they can do bareback if they show up with an STD/HIV test. And since all porn star girls are up to date tested too...it's as safe a sexual experience as you can have other than jerking off.
Now me personally? I never use a condom. Hate them. The statistics show that there is a better possibility of me being struck by lighting, falling down in the shower and dying, even having my personal home blown up by a "terrorist" than there is of me contracting HIV via sex with a woman.
It's very difficult for a man to contract HIV from a woman. Not impossible...but you have a 1:100 chance of dying in a car accident on the way to get laid (source:

My advice is for people to live their lives and enjoy them in whatever makes them happy. Nothing worse than living your life in fear to enjoy some good pussy spending your whole life scared with a condom and then end up in a car wreck or dead from cancer or heart disease or any of the hundreds of other things that are are far more likely to happen to you.
