puffy nips are a genetic thing bro. Im dont have a high % of BF but nips are still puffy. I know this is not gyno because they have been like this since age 14. Most people are selfconcious about this matter so they make their nips hard before taking pics. Lowering BF will help the matter but not make it go away. I hate wearing some tight shirts cause i feel like my nips are the only thing seen. It sux bro, but ya got to live with it..
