Hmmm cant beat an Irish accent, they have this way of telling a story too I could listen to my Irish friends for hours,
I can't really say Ive met THAT many ppl with interesting accents to tell the truth!
Oh I quite like a welsh accent too love the way Stacey talks in Gavin & Stacy haha!
On a man I'd say ermm maybe Italian or something that sounds quite sexy..?
Some American accents sound so whiney so I wouldnt put them on top of the sexy list!
