Swift, 24, said if a man dates more than one girl in his life, he is called mysterious but if a woman gos out with more than one guy, her character is doubted, reported Aceshowbiz.
"We (she and her friends) talk a lot about feminism and the inequality between the way men and women are talked about.
"The kind of things we say are: 'Why is it mischievous, fun and sexy if a guy has a string of lovers that he's cast aside, loved and left?
"Yet if a woman dates three or four people in an eight-year period she is a serial dater and it gives some 12-year-old the idea to call her a slut on the internet?' It's not the same for boys, it just isn't and that's a fact," she said.
