" There are no good research studies that evaluate the short or long-term effects of using butt plugs... short-term use probably is not much different than bowel movements, anal sex, or medical procedures. Long-term use, however, probably is." Mark P. Behar, PA-C quoted in Shepard Express "More on Wearing Anal Plugs Long Term" http://shepherdexpress.com/article-permalink-12522.html
