...if when you leave you are happy and satisfied with the service. Of course she would enjoy an orgasm but the nature of this is she might not have one and the session isn't about her. I enjoy talkng to the provider I'm with and I enjoy giving her oral. Sometimes she will orgasm sometimes not. Treat her with respect, enjoy her company, leave the correct donation, and go when your time is up.

That being said, many guys, me included do enjoy pleasuring our lady orally.  You are paying for her time and what you do with it is your business.  Some guys never have intercourse with providers, just oral and they are happy.
