I echo everything that has been said above. Especially the part about DO NOT DO BAREBACK WITH A PUNTER!!!!!
And yes once you've done a punter for money you're a prostitute full stop. You can call it whatever you want but it's still the same in the end!! Also I wouldn't tell them you're new to the industry they will try anything to get you to do something you don't normally do, they offer stupid amounts of cash. They will take the piss good style.
Really think about this luv & take your time.
All the best.
Luv Kate xx
