Years ago, when I read Elaine Aron's The Highly Sensitive Person, I could recognize the HSP people around me with the innate ability to sense, revel in, or be overwhelmed by their external and internal worlds. These folks (I'm not one) are the best cooks, among the most creative artists in any field, and make with their ability to track both minute changes in their clients and the corresponding responses in themselves, some of the best therapists. They also can be over-loaded by too many people, too much noise, too much light, too much commotion, and their intense awareness of their own internal states. See Aron's website with her books and other information, here.
I just read a lovely post by an HSP man, Rick Belden, coming out as Highly Sensitive and exploring issues of maleness as HSP. Every therapist and every HSP and interacter with HSP's (that would be everyone) should read this lovely post. http://rickbelden.com/blog/2012/11/16/i-am-a-highly-sensitive-man/
