Love my nipples played with. My wife calls them my "all done buttons" because after I've cum, they're too sensitive to touch, but until then, I like them played with firmly. A gentle touch is irritating to me; I like firm pinches, twists, sucks, and bites. Oddly, I don't like nipple clamps; I don't like the constant pressure or any but the briefest pain, but I like frequent, brief pressure. Like some others here, pinching them when I'm close will nearly always make me cum. My areola aren't large, but my nipples are, so that they pretty much take up the whole brown area, especially if I've been using my excellent nipple sucker bulbs. They are always hard and erect, never flat anymore, and I like to wear light colored shirts so that they make prominent bumps in the fabric.
