I nearly got caught at school. I would have been 14 at the time. I often underdressed in an afternoon when there would not be games or P.E. That day I had gone further than usual and at lunchtime at home I had 'borrowed' two of my mothers open bottom girdles. one was in the conventional position on my hips and the other was round my chest with the suspenders clipped to the top of the lower girdle. I went back to school in the afternoon and we had a lesson where the teacher started a theme on sensations on the skin. this involved people opening their shirts to see how far apart two pins placed on the skin had to be to be felt as separate points. I had quite a time refusing to open my shirt!. I didn't do that again although I quite often continued to wear my mothers knickers or girdles under my trousers. I often think about how near I came to being caught. I can't say I knew of any other boys who liked female clothing. In fact I still don't. :-)
