The one and only time I felt awkward was the first time we had to get changed in high school sport, we were not allowed to miss showers and everything was open and shared. Once over that small hurdle (no big deal after all), I've never felt awkward again...and I went to school in the 80's. We're all tall, short, fat, thin, fair, dark, smooth or hairy, cut or uncut, some of us have moles or blemishes, wide or narrow feet, big or small dicks, freckles, eyes of every color, pensioner or teen, so don't get beat up about using a gym or pool or joining a sport team just for fear of nudity among your gender. Forget the photoshopped models in soft porn or instagram, a small amount of bravery of the most trivial sort and it's all over and done with. You'll be baring all with the diverse inhabitants of the communal showers in no time and getting soapy and clean into the bargain
