I had already responded to a thread similar to this and I believe I said something like mine were nothing more than decor.
In the last two days I've had and equal number of quite astounding revelations.
One was that my Sansa Clip 4GB mp3 player, the one I thought better than the higher priced iPod 2GB Shuffle that I recently purchased as a gift; better because of its visual read outs, equalizers, custom modes, custom playlist capabilities, and effortless loading of songs (click and drop via Windows as opposed to having to download iPod specific software in order to load music files) turned out to be even better than I
originally thought because while fuckin' around with the buttons I inadvertently activated a hitherto UNKNOWN voice recorder and FM Radio. Whaaaaaaaaaa?? For two years now I've been carrying around this thing and only now discovering it's a recorder AND radio too?? jEEZ.
So what's that got to do with nipples you ask. Well a couple of days ago (after reading this post) I figured I'd try tweaking on my own nipples a bit while diddling me dong. What the hell I figured. Probably just bullsh---WHOOOA!!
Now I'm even aware of them rubbing against my t-shirt. WHAT the FUUUCK! Fifty plus years to discover my nips do more than just sit there. Damn!
