It's my first full day on this site, and after reading and responding to some of the other first time experiences, I thought I would share mine.
Reading some of the others, I feel mine is very boring, but will share anyway!
It was during the summer months, and I must've been about 12 years old. I couldn't sleep for some reason that night, not due to the heat, but I found myself very uncomfortable in my bed.
After a few hours of trying to get comfortable to no avail, I got out of bed and felt my pjs and pants were restricting me. So I took them off and walked around the house for a bit nude, very quietly trying not to wake anyone. For some reason, it just felt 'right' in a way I couldn't understand. I remember feeling thirsty, so I opened the fridge and felt a waft of cold air cover me, and it felt 'funny' at the time, but with hindsight, it was the same experience and feelings I felt when I first went nude outside a few years later.
After that night, every time I was alone in my room, and every night I went to sleep, I was naked. Over the years, I tried to be naked as much as possible, but at the time I didn't know if it was normal, or if I was 'weird' as there was no internet for me to search other peoples experiences of wanting to be naked.
