What a doofus.

My psychiatrist used to ask me outright. Occasionally I would tell him the truth. More often he would ask to see my arms, legs whatever. If I refused he'd wheel over in his chair, take my arm & roll up the sleeve. I never resisted, mainly because he had done it before I even noticde what was happening, but learnt to shrink away if I saw him coming.

Meh, I'd jump in a cab & go for sutures before I'd tell a psychiatrist again - apart from anything else they do not judge you or get squeamish at the casualty department & you don't get hassled afterwards.
