Growing up in New York, the future Olympian "would play dress up as a kid, just like anyone else,” a source close to the transitioning reality star tells RadarOnline.com. "However, as a teenager Bruce would take items from his mom, Esther's closet. It would be a sweater, or a loose blouse, and was always done behind closed doors.”

And sometimes, the source said, he'd even raid his mom's lingerie drawer. “His favorite items of clothing were silk and satin lingerie,” the source revealed. “He has always liked the way it feels on his skin."

"For years, Bruce had felt ashamed of it, and that is what drove his athletic success, thinking that would banish the behavior,” the source continued. "It just didn't, and Bruce has broken down in tears over the years, telling close friends and family about the shame he felt as a teenager. He now recognizes that there was nothing wrong with wearing women's clothes.
