Does answering yes or no to do you provide full service really incriminate the potential provider?  I was talking to a provider who has no reviews and trying to figure out if she is legit and said she couldn't answer a sexual question.  Who said it was sexual...maybe I thought I was calling a gas station.  Am I being unreasonable when this raises a red flag for me that they won't answer the question?  Any tips on what others typically ask?
