Here’s what I was looking at:
http://www.age-of-consent.info/states/Texas
First thing that came up on Bing.
Yeah, it says the same thing on that page too:
“While there is no close-in-age exemption to the Texas legal age of consent, it is an acceptible defense in court if the defendant is less then 3 years older then the victim and the sexual act was consentual.”
