Nevada requires condom use, regular std exams and HIV tests for sex workers, and the guy is examined on the spot for any signs of std's such as sores or discharges.

The rate is negotiated between the client and sex worker. They work as independent contractors so it is up to them, within a customary range.

Remember, it is illegal in Clark County (Las Vegas). And it is enforced, so don't get in trouble. Fly into Reno.

Why despise yourself? You have a fundamental biological need. Practice will make you a better partner when you do meet someone.
