When I was about 5 years old, I went to go pee, and when I started white stuff came out for a few seconds, and then it went back to normal. It obviously wasn't cum (I was 5) and this has never happened again at all.
This may be a problem...Are you a girl or a guy?? When i eat a lot of raw meat this happens to me. I need more info relating to this problem of yours in order to give you the most "thorough" Methos diagnosis.
What's the problem? You were 5 when it happened, you're obviously much older now, and it hasn't happend again. Whatever it was obviously wasn't serious, or you're experiencing a false memory. Let it go!
