Inguinal Lymph drainage
As for 'too personal', I would imagine that there will be certain techniques for hard-to-reach areas that may seem 'too personal' (especially sports-related issues). But I would also imagine proper draping could reduce *some* of it. I know that working deep to the glutes and working the ischial tuberosity may create issues. But once you are no longer doing fluff & buff services and more clinical work, I think then the issue of propriety may become a perceived problem.Just my 2 cents.
