I’m not sure if Nipplegasm is a real word, but I’m willing to argue it should be. As this Guardian article explains, nipple orgasms are a thing.
One big part of my kinky journey has been learning to develop erogenous zones and in particular the nipples. Previously I treated them as pointless fleshy chest blobs. Now, after years of incorporating them into kinky play, they’re magic buttons of pleasure. I’m not sure I’ve ever had a pure nipple orgasm, but they’re certainly a big part of my play. Worth working on if you’ve not yet done so.
