When girls nipples get played with why do they go hard?

Answer 1

Oh, dude, it's like a fun science experiment happening on your chest! When nipples get stimulated, it sends signals to your brain, which then tells your blood vessels to tighten up, making the nipples hard. It's just your body's way of saying, "Hey, something interesting is happening here!" So, like, enjoy the show!

Answer 2

Well, honey, when those little nips get some attention, it's like a party for your nervous system. The nerves down there send a message to the brain saying, "Hey, we're feeling good!" That message causes the blood vessels in the area to constrict, making those nips stand up and say hello. It's just a natural physiological response, nothing to be shy about!

Answer 3

When a person's nipples are stimulated, it can cause the smooth muscle fibers around the nipple to contract. This contraction is controlled by the autonomic nervous system, specifically the sympathetic nervous system. The sympathetic nervous system is responsible for the "fight or flight" response in the body, and one of its effects is causing the smooth muscle fibers in the nipple to contract, resulting in the nipple becoming erect or hard. This response is a normal physiological reaction and can vary in intensity from person to person.

Answer 4

Most females nipples go hard when excited, cold or Wet.
