The first time anyone but my mother or my father saw me naked, was my younger sister. She did not know that I was in the shower, the door was not locked and she came bursting in. When she saw me, I think she was more embarrassed about it than I was. She quickly closed the door and ran back to her room. After I got out and dried myself off, I wrapped the towel around my waist and lower part of my body. Then I left the bathroom. To get to my room, I had to pass by her room. The door was slightly ajar and she saw me walking by. She said that she was sorry that she did not knock on the door first to see if I was in there or not. I told her not to worry about it that I was okay that she saw me naked. Our parents were not at home and I asked her if she would like to take a better look at me naked. She said that she would like to if I would let her. I removed the towel and told her she could look at me. I did a complete 360° turn around for her and then walked to my room. After that neither of us were concerned about seeing the other one naked. No, we did not think about any sex with each other. All though I did get hard in front of her a few times when I was naked in front of her. Especially if she as also naked in front of me. She did not have her breasts yet and I looked closely between her legs most of the time. When she started to develop her breasts she would push them out really hard to make me look at them as well.
As for my bein naked in the locker rooms at school, it dd not bother me in the least bit. I did not really look at the other boys as sex objects and I do not think they looked at me as sex objects. So, it did not bother me at all.
As for being naked at other times in front of others, the first girl beside my sister to see me naked was when I was 14. I was living in France and was dating this very beautiful French Girl. Her and I once took off our clothes in front of each other. The only thing that we did that could be considered sexual was to feel each others bodies. After that, I did not mind being naked in front of anyone, boys or girls. Today, I like to be naked in front of others, but not in groups larger than 10 males or 10 females at a time.
Of course, when I am acting as a sub to another male, or group of males, I feel that it is only proper that I am naked in front of them. As for them being naked in front of me, it all depends on the situation at hand. If they are going to have any sex with me, I do expect that at least at that time they will be naked.
As for my sexuality, I am bisexual, about 20% to 30% gay and the rest of me is straight. I do like to submit to males and be Dominant or submissive to females.
