I think I have mild tactile defensiveness. Nothing too distressing.
I have sensitive skin any way.
I am more sensitive to the touch than normal people in some areas of my body and shy away from hugs etc.
Although this lack of wanting hugs from people, may be a psychological issue rather than a tactile one.
I also do not feel the cold as much as normal people.
I am not super hypersensitive, as i was able to train in martial arts at various times in my life, without any problems.
Including Judo and BJJ for a bit. Both tactile throwing and grappling arts.
I have heard that some feel extreme physical pain if touched. Which must be very distressing and difficult to manage.
I sympathise with you if you suffer from this symptom.
