That law is not enforceable anymore. Otherwise every adult store in Texas like New Fine Aets would already been shut down.
These laws were made long time ago by ignorant people and using archaic outdated values
The Texas obscenity statute is a statute prohibiting the sale of sex toys in Texas. The law was introduced in 1973, and was last updated in 2003. While the law was never formally repealed, in 2008 a U.S. District Judge released a report declaring it to be "facially unconstitutional and unenforceable."
On November 4, 2008, U.S. District Judge Lee Yeakel released a two-page document dated October 29, 2008, in which he stated that the Texas Attorney General's Office notified him that they would not file a writ of certiorari with the Supreme Court. The next month, on November 13, Yeakel filed a "joint status report" that noted the parties had come to an agreement. "Texas Penal Code §§ 43.23, to the extent that it applies to 'obscene devices' as defined in Texas Penal Code § 43.21(a)(7), is declared to be facially unconstitutional and unenforceable throughout the State of Texas".
At one time in Houston Harris County it was illegal for anyone to possess more than 3 dildos unless they were a doctor with a valid medical license... that law is no longer valid.
It's like the Texas Sodomy law and similar laws in other states, which has been struck down
https://en.wikipedia.org/wiki/Lawrence_v._Texas
in 1998 2 men in Houston Harris County were arrested for having sex which is against the law in Texas under the Texas Sodomy law
Texas Sodomy Law also doesn't just cover gay men, it covers all adults when it was in effect
A woman performing oral sex on a man or a man performing oral sex on a woman or two women performing oral sex on each other, those were illegal under the Texas Sodomy law.
Anal sex between men and women was also illegal and even anal sex between two women using sex toys.
So those 2 men fought it all the way to the U.S. Supreme Court in 2001 and
The Supreme Court struck down the sodomy law in Texas in a 6–3 decision, and by extension invalidated sodomy laws in 13 other states, thus protecting from governmental regulation throughout the U.S. all forms of private, consensual sexual activity between adults.
