Should I get breast implants?

Simply put: Most men like bigger boobs, or at least boobs that are proportionately larger than your frame. (Having huge saggy boobs because you are obese with a pot belly doesn't count).
There are slight variations -- American men like enormous boobs, and the more rural, the bustier they want them. New Yorker men are not adverse to big breasts, but some of the more sophisticated clients can be turned off by obviously trashy, unnatural boobs.
While nobody is going to complain that you're busty, Europeans and Asian are less taken with busts, and generally want a more proportionate body.
(Side note: Europeans and Asians are also less forgiving when it comes to fat. Meanwhile, black men are the most forgiving to chunkier girls).
So... do you have surgery?

Say no if:
You're just starting out . Wait and see if you want to work in the sex industry long-term.
You're just stripping one year to pay off a student loan. That is, unless you want big boobs even after you become a lawyer, accountant or whatever.
You're broke. It's not worth going into debt for.

However....
If you are naturally very flat chested, consider it. You can go up a cup size or two, and it will still look natural and you can keep them after your stripping days.

The best candidate
* Has saved up some money and time off after working in the industry for a while
* Feels she definitely wants to stay in the sex industry and make a career of it
* Really feels she will look better and make more with bigger breasts
