Is it normal to like rubbing rubber bands?

I found my way to this wonderful site because I became curious as to whether or not I was alone in the world with my own particular perculiar habit. I found the posting where people admit to liking the sensation of rubbing tags, blankets, silk, etc BUT no where did I see that anyone has this habit with rubber bands! For me it has to be a particular kind of rubber band. It must be a certain width and texture in order for me to obtain the sensation that I like when I rub it between my thumb and first finger (or lay it in the palm of my hand while simultaneously manipulating it with all of my fingers to get that soothing sensation). I've been doing this since I was 6 or 7. I can't remember when it started, exactly, but my earliest memory of doing it is that I remember being instantly soothed--almost to a state of catatonia (lol). I had a particular stressful childhood and must have stumbled on this in some kind of way. I never sucked my thumb or rubbed any other materials when I was a baby. Just one day it was eureka!
