Keeping my knees and ankles together was difficult for me, holding them together in a upright position worked the best for me and to have my legs at a angle looked better and more feminine but it was even harder to sit in that position for any length of time.

Mom could see this so she had me cross my legs and wala that was the answer for me, it really felt way more comfortable and natural crossing my legs, so that became my sitting position from that morning on, plus I really kinda loved it.
