A survey asked for opinions on the most attractive accent in America, and the results show it's not just a southern accent, in general, that's cool. There's one specific part of the South that talks sexier than all the rest, and that's us. Texas is sexy Y'all!
When you ask a European for the sexiest accent in the world, most of them will say it's someone from the Deep South (from Georgia over to Louisiana).
Texas is in a land all by itself, and that "Texan" accent ranks high too.
