I did search the forum (nipple AND shirt) before putting this up, came up empty, but can't believe I'm the only one to have experienced this. Driving along with my two freshly filled 510s in my shirt pocket this morning, I noticed just the slightest discomfort right beneath my pocket. Now, speaking for myself, I have no idea of why we male humans even have nipples, and I know mine are as sensitive to pain as they are useless. Anyway the sensation was like a slight burning or chapping--not excruciating, but a bit alarming until I figured it out. Evidently, the tiniest amount of cartridge leakage or residue from filling must have blotted through my shirt and hit its target. Not my preferred method of nicotine delivery...
