I can't speak for the toilet thing... but panties are AMAZING! It's very clear to me why so many men have panty fetishes. It's an intimate piece of female clothing that we don't normally get to see women wearing. When you do see them, you're seeing the "forbidden". The feel of women's panties (particularly classic-style full-cut nylon brief panties) is very sensuous, silky soft, feminine, and particularly naughty feeling for a man to touch. And if a man dares to wear them, I think almost without exception he'll become hooked on the naughty erotic feeling.
