I'm from the Midwest U.S.
From the rest of the U.S.: Southern accents are alright, and while I found some Southern women attractive, it was not because of the accent.
Outside the U.S.: Mostly the same thing with British, Australian, etc. accents. Although I did hear a British woman with a sexy voice (I think her accent was Received Pronunciation) online, though. I've also heard sexy Australian voices.
As a linguaphile, I just dig accents. I might have some favorites, but don't think her accent would be among the criteria that have any impact on a woman's attractiveness to me. That said, I have dated a preponderance of Latinas, purely coincidentally...
shareI love Mexican accents. They have a sort of lazy slurr.
It depends on which accent or dialect. I dislike Boston, but like Southern. I dislike German, but like British, French, Italian and Irish.
shareEnglish is my 2nd language and even though I'm fluent, I'm having a hard time understanding accents the further away they are from plain English.
I little bit of an accent is fine, but I don't find any particularly attractive.
There are even movies in English I cannot watch without subtitles, because I understand less than half of it.
