I love a good massage, whether I get an HE or not, there is just something awesome about massage in general for relaxation or riling you up depending on what you ask for.
Now, do not get me wrong, finding a young and fit 20 something masseuse to rub her hands all over me is very nice, but!
Experience is much better IMHO, knowing where to use the right amount of extra pressure and where not to is important and makes a world of difference in the experience.
The old adage, With age brings Wisdom, this is immensely more important in massage.
I have not seen her yet, but have read CaitlynKennedy's reviews and while I would not call her old she has the experience and would probably make you scream if you let her. You'd do well to give her a call.
My massage ATF is not skinny but is around the same age as CaitlynKennedy and is easily the best massage you'll get where I live, worth every dime. The fact that she provides an outstanding HJ finish is merely a bonus, I'd tip her the same even if she did not provide it.
You might just want to rethink the body type thing, at least to try it once. You'll be glad you did.
