do a search here and put very muscular in as the body type- several come up that aren't really bodybuilders but some are-  also depends what you are looking for a lot of bodybuilders provide muscle worship/ wrestling - some allow dfk, daty and/or bbbj while others are just hj- others will provide f/s- a good source is wb270.com you can look by area and also the travelers list is a good place to look-  on the wb270 list some to look for who visit DC often and provide f/s (many have reviews here)- Nadia M, Clarkflex, Wildkat, also under the Washington DC area there is musclebunny (i think she used to have reviews here and she has advertised on eros) and Maria Calo (think both musclebunny and Maria are f/s but could be ymmv), also on wb270 list Absolute Muscle coming in August (don't think she is f/s but have heard good things about) and also Figure Power (who has reviews- website fitflexing.com) visits fairly regularly

when you do the search for very muscular here you get reviews for Nadia M (from Carolinas)- but visits often- Musclebunny/ Michelle (discussed above), Barbara Barnowich (DC), also Diva (Maria C- discussed above), Figure Power, Emma Turlington (local to DC- more fitness than bodybuilder), Ginorma Butler visits but not f/s, Debra D"andrea (visits)- So there are some to pick from, do your homework though because services offered can vary
