A childhood belief about periods

When I was younger I learned about tampons. Well, I can't really say I learned much about them... Actually, I was quite disgusted with anyone who used them. You see, I knew about sex and everything, and I knew the place where a man's 'tool' is put, was the same as a tampon. I also believed that a tampon was just a plastic tube, ((Due to the plastic tube it's in.)) And since, you never see the rest of the tampon after use, I had nothing to argue against me.
So, due to my knowledge, and lack of knowledge, I believed that a tampon was a plastic tube that was insterted into a femaale and filled with blood during her perion. I also believed, due to what I believed a tampon was, that it doubled as a pleasure device. ((Like a dildo))
Both me and my friend believed this.
Boy did I feel stupid when I found out how they really worked...

On a related note. I know someone at my school who put a tampon in for the irst time without reading the instructions or having someone tell them about it, and so she didn't take the plastic part out. ^^;
Oh well. Live and learn, no?
