My older brother told me going back to really young I was fascinated by guys bushes and always wanted to touch them. He took me to beach a few times and when him and his buds were changing I embarrassed him but they laughed it off I was a curious little kid. I think that till today its why the more thick bush a guy has the more I'm turned on.
I used to love to piss on myself too, I was a bed wetter and when I outgrew it used to love to pee on myself and then realized it turned me on to piss in my pants. When I was a teen an older guy used to get me high and have me shit in my pants for him. I loved the way it felt when I first shit but when he would open my pants and started playing with it the smell made me throw up a few times.
