I should have done it
When I was 17 a girl I had known for a few years and I went swimming. When we returned to her house I went into the bathroom to change. The door had an old-fashioned lock with a keyhole. I was about to change when I hear "I see you." I froze and stood there for probably five minutes until her mother came along and told her that was not nice. I regret not having stripped. Maybe would have led to some sex education. Sorry Sandra.
