A Blow Job Will Cost You 10 Years

[Galt]

But because of an archaic Georgia law, it was a misdemeanor for teenagers less than three years apart to have sexual intercourse, but a felony for the same kids to have oral sex.

I keep reading this and re-reading this to see what I'm missing.

Are they saying that it's NOT a misdemeanor for teenagers MORE than three years apart to have sexual intercrourse? If not, that entire sentence serves no purpose. If it's just illegal for teenagers to have sex, then why not write it that way.
