This isn't really my belief...
When I was 15, I had my first "serious" boyfriend [still serious 4 years later]. One day, we were talking on the phone, and I was complaining about my period [as always.] I think I used the word "heavy" to describe it about 8 times before he said "I don't see what the big deal is, it's just a little dot." And I said, "what?" To which he responded on the sanitary pad commercials, they only poured a little dot of water on the pad to show how well it worked, and he had therefore assumed that that was what a period was like for a girl.
I asked him if he thought it was blue, too.
