It's a work like another, some people can fit for that.
But I advice to not doing this if it is illegal in your country/region. It can end up bad with both law or possibly with very evil people, like mafia ones.
You should also avoid race-mixing, you can specify who you accept as a client.
Now, personally the girls I saw doing this, have all a similar aura, maybe it comes with the job, or with being with a lot of people.
Being with a lot of people will create many bonds with strangers, and it can be draining and dirting.
That's your choice in the end, just think about it 360 degrees.
Another way to "sell your body" is by modelling, you basically need a good camera and some lights, you will have good photos to sell.
It can be more clean, but let's hear also what others have to say, and it's not neccessary sexual related, there are many paths there too.
