In response. Congratulations!
Massage without a towel is much less risky and much more sensual. Of course, washing the hands thoroughly before giving a massage is essential. Dry hands and palms harbor tinea corporis and bacteria. A good washing of the hands with a lot of soap and a good scrub of the palm would get rid of most tinea.
If the hands and palms of the person giving the massage itch, make sure the hands and palms are thoroughly washed and they no longer itch before touching anything.
