I am going to repeat what others have said, and like them, I've been doing this work for DECADES.
Do not apply for a "job". As a sex worker, you are self-employed and in control of your own work.
Agencies are PIMPs (ie criminals) and not to be trusted and are best avoided.
If you don't have a place to offer incalls AND you have never done this before then go work in some BROTHELS AKA massage parlours - be friendly with all the women who work there and soak up all their stories.
Mostly they will give you good advice.
Trust 0% of the men - MOST (but not all) of the men involved in running agencies and brothels talk absolute SHITE and listening to their advise will not keep you safe or help you earn money.
A tiny % of the men are OK, but you won't know straight off.
The aim is to Learn the ropes from women who do the job and set yourself up completely independently.
