I have been going to him 1x a month for past year. There is no draping and he is clothed during the massage. He is very discreet and protective of his license. I believe it is a YMMV situation.
He has shared with me the type of nut 🥜 jobs that have called him. So don't expect to get much info from a phone call.
He also seems to pick and choose who he will work on.
