I can’t speak much to USA, but in many Thailand and Vietnam spas it’s offered as a service in standard and FS spas. Here is USA I have a girl in a KSpa that shaves me all over every time I visit in the table shower. I did get a HJ/bj combo the one time I went to a Azn/Brazilian wax spa, but it was too crazy to do regularly. No privacy, can’t make any noise. It was a nail shop too, and a large number of housefraus were getting nails done while the girl was playing behind a curtain in the back with me. I didn’t ask, wasn’t expecting it. She just asked if I wanted all the hair removed, and it started happening after she waxed my shaft.
