"Perturb your sensitivity" ? I find that hillarious! ...Oh, and I totally understand.

This was pretty much what my old Chinese sifu said about body-building and Wing Chun. It can really get in the way of reaching the highest levels of skill. On the other hand, if you are going to fight, it absolutely helps to be strong. This guy was one of the fighters in our system. Of course, he never touched weights.
Is he single?
