I grew up in a very religious family. dressing in sexy clothing or snug swimwear at the beach and nudity at home or anywhere with family was considered a no, no. When dad passed away My uncle always took care of me like a second father, but I didn't get to spend any real time with him until I was over eighteen. I was always very shy about sex and nudity due to my family's beliefs. While in college and in my early adult years, I was invited to stay overnight with my uncle. It was on Halloween night after being at a nice costume party with classmates, dressed as a superhero in blue leotard and tights with red speedo briefs over them and clinging white nylon briefs underneath. My costume really felt nice and was giving me quite a hard on, yet feeling a sense of shame about it. I arrived at my uncle's home still in costume, when he greeted me at the door. He gave me some nice compliment about my superhero costume while noticing my erection outlined under the leotards. I was some what embarrassed, when we had a long encouraging and educational talk, soon making me feel better about my self and nudity, when said, he will help me out of my Halloween costume. I was blushing now, as he escorted me to the large polar room with several large mirrors and clothes hangers for adult nudist guests He had a set of baggy pajamas with a change of clothes for me to wear in the morning. I shyly agreed and It was beautiful, as he gently removed my superhero yellow boots, long red cape and the make believe power belt. I had a lot of nervous anxiety, yet very sexually excited now, from the feel of the tight spandex material and his warm hands. He would give me a few warm hugs while saying for me not to be ashamed having a hard on under my superhero leotard and tights, nor embarrassed or ashamed, once I have your costume all stripped off and naked. He was wearing only a long fuzzy bathrobe and had a noticable semi erection underneath. I began really feeling good, while he slowly stripped off my superhero leotard, tights and clinging undies, layer by layer. He kept reassuring me to have no fear he will hurt me, nor shame being in the nude, but proud of my still young adult body, once he gets me out of that tight spandex superhero outfit. It was beautiful, slowly and gently, everything soon came off. I was now totally naked with a full hard on and feeling no shame baring it all with him. it was a good and memorable start for me being naked with others. A few times during the summer, we went to a nice swim club, of which he was a member and I was meeting other nice people including many lovely nice young women. We would change out of our wet swimsuits together, and feeling no embarrassment being naked in the locker rooms. Sometimes at his home during the warm weather, we'd sit out on the porch, with me wearing one of my new bright colored, extra snug speedo swimsuits outlining a full hard in them. later we would go into the bathroom, him completely naked and me still in my tight speedo. He would say" it's time to change, so let me strip off this tight swimsuit off." Again, it felt so nice, as he pulled and tugged on my speedo, slowly coming down, then my erect penis would spring out, while he cheered for me not blushing in shame, when he soon got clinging speedo briefs unsnugged, down and off me. It felt so good being naked with a healthy erect penis and a nice way to grow up as a young adult male and being proud of my body
