So I am in my new "sussy" diaper from ABU. I noticed something but not sure of it. On the side of the diaper the part that's touching the inside of my leg, theres a flap of material. I call it a pocket..whatever. anyway. I just found out without realizing it that my "boy part" slips fight into it and now its all nice and snug, not moving around. Feels nice. Is that what its for? Anyone else do this?
