Advice for traveler

I'm coming in June (Nairobi) for a few days and would really like to make the most of my time there. I've been doing some reading online and I have a few questions:

- The exclusive clubs seem out of my price-range. Is the experience worth the cost?
- Where/how can I find the most beautiful girls, and not get robbed blind?
- I understand that the HIV rate is the highest in the world, nearly 1/3 of all sex-workers. Is this something I should be concerned about?

I'm fairly new to the hobby, please answer as if I know nothing at all.
