Squat or sit?

Having been an EFRO aficionado since the dawn of my manhood, I often had lovely conversations with women about their bowel movements. One young lady, a short term colleague of mine in her 20s once remarked she needed the loo but she was so constipated so probably needed to squat to get it out. Upon hearing that, my loins went camping 'cause it pitched a tent.

Which leads to the question - a women squatting or sitting to poop, which one's more arousing? And for the women, which position is your favourite for pooping?
