Jeez! When I came to Greece, tactile people! everybody started to touch me all the time
- When they laugh with you they will put their hand on my shoulder
- When they friendly introduce you to someone they will put their arm around my neck
- When they want to show you something, they will grab your arm
- When you said you knew nothing about their favorite soccer team (there are 3 major teams in Athens so I my legendary luck failed me all the time) They will grab you and rub you like "raaah... bad guy!"
The first months it froze me all the time, after a year of observation and constant discovering by surprise (no preparation possible I think unless you become paranoid), I just kind of started to do it myself, silently thinking: "ha you see, I can rub you too!"
After a couple of years I still have a little bit a surprise and I touch other with a bit of premeditation. But for them it is natural, like an extent of their feelings, a whole part of a thing to say.
So for the advice, I did martial arts for quite a long time and it was a completely different kind of touching: useless
The brush might work if it is someone else brushing you, I felt a little this odd feeling of being touched when I had a massage, maybe you should try and tell the masseur that you want to get used to surprise touch.
