Your nipple sure do get hard that's all i know
Nipple hardness in males can occur for several reasons, including hormonal fluctuations, arousal, or temperature changes. The body can respond to various stimuli, leading to the contraction of the muscles around the nipple, making it feel hard. Additionally, conditions like gynecomastia or certain medications may also contribute to changes in nipple sensitivity or firmness. If there are concerns about persistent changes, consulting a healthcare professional is advisable.
I would press charges. That is abuse.
