A new study suggests that more than half of the women population are attracted to other women. According to a latest research, it claims that it is perfectly normal that most women are naturally bi-curious when it comes to sex, and it becomes more pronounced the older they get. Boise State University found that in a group of 484 heterosexual women, 60 per cent were sexually attracted to other women; 45 per cent had kissed a woman, and 50 pe rcent had fantasies about the same sex. A professor of psychology at Boise State University, Elizabeth Morgan, found that straight women often feel more than a friendly affection for other women. Other data suggests upwards of 20 percent of women are attracted to other women. It\'s claimed this could be linked to the way women socialise from chatting on the phone for hours to snuggling during chick flicks. It is said that often women\'s friendships are barely distinguishable from romantic relationships. \"Women are encouraged to be emotionally close to each other,\" the Daily Mail quoted the professor as saying. \"That provides an opportunity for intimacy and romantic feelings to develop,\" she added. Another psychologist, Lisa Diamond said that the older they got, the more likely they were to choose \'unlabeled\', which meant that they felt their sexuality didn\'t fit into tidy boxes.
