Facts and figures are completely meaningless in this capacity. Either you get an STD or you don't. There is no way to accurately determine the probability of your contracting a disease based on what the profession of the woman you sleep with is. In short, if the girl has a disease, and the condom breaks, you're screwed. If she doesn't have one, and it breaks, you're okay. If she doesn't have a disease and the condom breaks, you're okay. If she does have a disease and the condom doesn't break, you're okay. If she doesn't have a disease and the condom doesn't break, you're okay. If she's a waitress and she has a disease, and your condom breaks, you're screwed. If she's a stripper and doesn't have a disease, and the condom breaks, you're still okay.
Since this question is rather pointless and has no accurate answer; closed.
