Right now, touch is essential for my healing. Even though I'm still uncomfortable with women or doctors touching me, I love massage therapists and have been seeing an accupressure practitioner who is also a psychotherapist who specializes in anxiety disorders, so I kill two birds with one stone, so to speak. Right now a big part of my current problems actually stem from the LACK of non-threatening physical contact (I train martial arts, but have few friends outside of that sphere). It really depends on the circumstances surrounding the touch, but right now massage and hugs are necessary (only from a few specific people!!). Like others have said, asking permission and treating each person as an individual by personalizing each session is key.
