Exactly. I remember those genital wart pictures from sex ed in high school. They were also pretty extreme looking. That's what I figured they looked like. Then after contracting HPV, and reading up on it...imagine my surprise! There's been many times I've read where a person's had something they didn't think twice about before. Then when they get it check out, they find out this whole time it's been a wart. They had no clue, because they figured they looked like what you'd find in those extreme pictures.
However, it probably causes some people to think they don't have warts because their symptoms are not as severe
