Is it normal to love my baby blanket?

Hello I'm a 25 yrs old male. I was sitting around thinking about my "obsession" or "addiction" that I have had with my blanket since I was still in diapers and still at the age of 25. When I was a little I can remember having this lint cotton blanket that I would rub between my fingers or my face, and on lips while sucking on my tongue. I remember the feeling it would give me such comfort and just felt so good to me. I remember I felt as if I needed my "mmmmm blankie" everywhere didn't matter. When I was younger I would also make a noice that sounded like mmmmmm as I got older the notice stopped but the rubbing and sucking of my tongue continued. my blanket is in pieces now but I always took a piece hidden in my pocket went I went out of town or to a sleep over. I'm not so hooked now but when I feel any material that is linty cotton I still find my self sucking my tounge and rubbing continuiouly.
