Thank you for posting your story. You are a very strong person, and I admire your ability to rebuild your life under incredibly challenging circumstances.
Even if your only reason for declining sex work was out of a lack of interest, and you had an idyllic childhood, Tommy has no business belittling you, or questioning your motives. Your opinions of what you want for yourself should be respected.
I say you go with your instincts in not disclosing your story to Tommy. The situation sounds complicated and more than a little hostile.
