I don't know how often I was caught cross-dressing by my parents. I did it from as early on in my life as I can remember, as I thought I was a girl as long as I covered my hair and teeth and ddn't wear boys' clothes.
My mother in particular always made me feel very ashamed, especially after I found out that I really was physically a boy, but I couldn't help, myself. If people she knew recognised me while I cross-dressed, she was especially ashamed of me.
The scariest time I was caught was while I was camping by myself in a national park many years ago. My clothes were pretty unisex but I had painted my toenails bright red. For that reason, I used to shower late at night when the camp was quiet. It was a six week camping trip and up to then I had had no problems when I walked barefoot to the men's showers (I didn't dare get caught in the women's). I like walking barefoot in nature, and the shower cubicle doors in some camps didn't reach the floor anyway, so there wasn't much extra risk in spite of my toenails. On this occasion, someone came in while I was showering. There was nowhere I could hide my feet. Whoever it was didn't say anything and left after a little while. I saw nobody while I walked back to my campsite.
By coincidence, the only time my mother caught me and didn't say anything was when I got out of a shower and had forgotten about my painted toenails. She just glowered.
