Good for you being open to explore your gay side.

When hiring an escort read his profile AND reviews. http://www.daddysreviews.com/ is an excellent source for reviews.
Remember in most locations prostitution is illegal so don't expect the escort to agree to specific acts. You're paying for his time only.
Discuss your desires and fantasy of being with a man. A good escort will be forthcoming and tell you if he is a good fit to be a teacher.

Remember to treat him nicely when he arrives. He is a person and not an object. Offer him a drink and to sit and chat for a bit; for his safety have a bottle of water or a canned beverage that he can break the seal opening. He will usually ask for his fee upfront. Don't be offended as he is a businessman first.

If he does a good job a tip is always appreciated.

Have fun!
