I guess I was about 10 or 11... anyway, whenever my best friend came over and spent the night she would make us watch pornographic movies late at night. I didn't know very much about sex at the time, so during the movies I would constantly get up and go to the bathroom, only to find out that it wouldn't come out. I finally told my friend, "Whenever we watch these movies I always have to go pee, but it doesn't come out". She replied by telling me that I was "getting horny". (This is strange because she was a year younger than me...)
That's not all. A few weeks later I had the urge to go to the bathroom, but nothing would come out. My mom was in the bathroom with me at the time, so I said "Mom, nothing's coming out. I must be horny". The look on her face was priceless... needless to say, she asked me where I heard that phrase and what I thought it meant, and she set me straight right there... (But she didn't know that me and my friend had watched those movies ;P)
A childhood belief about sex

- I thought that there was a law that all movies had to have a happy ending— Quatsch
