In the area I'm in, there are 4 massage therapists that offer sports massage or therapeutic massage (without ANY type of sexual activities.) I visit them from time to time. I still play sports at may age and yes, it is very useful to have a massage that focuses on these areas. Your local paper, craigslist and yellow pages will provide that information. If this person is around for that reason, they must have (for most cities) a permit to operate within that town/city they work in.
Good luck.
