The legs parallel is a sign of femininity because men aren’t easily able to perform this posture for obvious anatomical reasons and because it makes women’s legs appear toned. Men have much narrower hips than women, and an extra bit in the way, and so therefore aren’t able to sit in this fashion! The parallel legs posture occurs with one leg pressed against the other making the legs appear sexier and more youthful. Women who are trying to draw sexual attention to themselves use this sitting position. The most overt sitting posture of all is having legs spread and will attract the greatest amount of sexual attention, but appears much more crude and less feminine.
