As a sub I have my entire body waxed before a session. I have all of my body hair removed from my neck to my toes. One mistress that I serve prefers a completely smooth body. Another mistress appreciates the hair free skin. I feel more naked and submissive when I am completely smooth.
In addition, the waxing process is a form of light BDSM. I am completely nude during the entire process which encompasses clothed female, naked male submission. There is also the pain of having the hair pulled out from my skin.
