There is no dildo limit anymore,
UNLESS you reside in one of the twenty backwards assed counties that fall within the Texas 13th District Court of Appeals (Corpus Christi area)!
Sooooooo based on the wiki info you are safe from prosecution for having dildos in your possession and you are safe to sell adult devices! I guess that's good news, still it's kind of wild that there are those out there that have some sort of vested interest in what I do in my bedroom and try to write laws about it? BIZARRE!
I also found the following sentence to be on a whole new level of disturbing...
