My experiences have been generally good. A few have been really good, None have been bad.
My main problem with massage therapists is that most do not/will not massage my glutes with the same attention as they pay to other parts of my body. Before I moved across the country, I had found a great massage therapist who considerd the glutes to be an extension of the back (Duh) and an extension of the legs. Therefore, he worked them from directions. This was strictly legitimate. The glutes are the larges and hardest working muscles in the body. Most men have lower back pain.
In my opinion, masage therapists who do not like to touch naked people have a problem. That said, massage therapists have to deal with inappropriate behavior and development of trust is a mutual process.
