Feeling pillows?

Ok so I have this habbit where I love to feel soft pillows or the stuffing in them. Like I take part of the pillow in my hand and I rub it with my fingers, it kinda looks like the hand gesture for money but slow. And while I'm doing this I fold my tongue over, the tip is facing the back of my throat, and I suck on it? And I can sit there all day and just feel a pillow. When ever I see the pillow section in a store I use to find a soft pillow and feel it, it's hard for me to just walk right by one. I can also do this by feeling unpierced ear lobes, but I prefer pillows. Is this normal?
