This is something I've always been curious about. Once, as I was trying to clean out my bellybutton (I don't have an 'innie' or an 'outie', more of a 'middley', it's shaped like the letter c) I stuck my finger in there and felt a prickling in my clitoris. Now, sometimes when I'm aroused I've noticed that I feel a tickling sensation in my belly button. Does anyone else get this too? I'm not concerned about it or anything, just curious.
