No offense, here is a copy/paste - post from UrbanDictionary:
"masseur
Generally considered to be a man who practices massage therapy, however this is a misnomer. A masseur is a man who practices massage and has none of the western medical training and is not licensed and may be associated with prostitution. In most states this is illegal.
I did not spend 15,000 dollars on school to become a masseur. The start up for prostitution would have been much cheaper but I wanted to make sure I didn't do anything stupid like perform hot stone on a client with severe heart problems so I became a massage therapist instead."
Anyone who went to school and is licensed will refer to themselves as Massage Therapists.
