Dating as an escort is a very common concern. Most likely it will remain to be until a time when there is less taboo around sexuality here in the United States.
I am asked most often if one should tell the person that they are dating. I feel this is a moral question. It is really based more on ones belief system. There is no right or wrong answer. There is only the answer that is best for you.
I would suggest you ask yourself the following when deciding which decision is best for your situation.
1) How will you feel about yourself if you are not honest?
2) Where would you like to see the relationship go in the long term?
3) If you are not honest initially. Will this person be hurt by finding the truth later on?
My personal dating experience is limited. I prefer relationships were I can be honest. Therefore, finding someone able to accept my career can be tricky. It is something I am comfortable with. At the same time it makes the relationships I do have that much closer for having shared my experience.
At the end of the day it is about what makes you feel comfortable. You want to have a healthy happy relationship. How you create that is ultimately completely in your control.
