Wut? This is, umm, complete and totally false. Where do people come up with this crap?
Texas Penal Code 43.21 DEFINITIONS (7) "Obscene device" means a device including a dildo or artificial vagina, designed or marketed as useful primarily for the stimulation of human genital organs.
Sec. 43.23. OBSCENITY. (a) A person commits an offense if, knowing its content and character, he wholesale promotes or possesses with intent to wholesale promote any obscene material or obscene device.
If I made this up, people would tell me it was laughably unrealistic :)
