Why do i have pecs with i'm cold and moobs when i'm warm. my pecs seem flatter when i stand up, when i'm warm my pecs seem to come to a point, why?

Common complaint: I hear this often from men presenting with concerns about gynecomastia. Because there are muscle cells in the areola surrounding the nipple, stimulation or cold temperature may produce a contraction that makes the nipple more prominent but the areola flatter. With warmer temperatures the areola relaxes and may protrude. Think about relaxing your stomach muscles and having your belly bulge out ward
