I would not judge you as I too self harm. I would instantly recognise your scars though & I would ask you outright if you self harmed. I think it would make me feel that you could connect with me, but I would probe you to make sure I felt you were able to cope & were in control. I would say to you, to expect some personal questions which personally, boundaries or not, I would 'need' to know to make me feel ok.
