If you're looking to gain sexual experience, I don't know if I'd recommend an AMP. The AMP experience, while fantastic, is very formulaic and the extras you're looking for vary widely depending on place & provider.
Instead, go with an independent escort, a real pro from Eros or Tryst. It'll cost a bit more but you'll get your money's worth. Don't be shy about telling them you're not very experienced. You won't need to impress them and they'll accommodate your specific needs. Mature providers tend to be better at this, but younger pros get the job done if you're upfront about your inexperience. Communication is key to getting what you want in every aspect of life - personal relationships, business, whores, restaurants, car dealerships, everything.
