According to research, the skin of the superior quadrant is the most sensitive part of the female breast. This means the upper part of the breast, closest to the collarbone, is most sensitive to touch and stimulation.
The areola (the dark area around the nipple) is less sensitive than the skin of the superior quadrant, and the nipple itself is the least sensitive.
It's important to note that breast sensitivity can vary based on individual factors like breast size and ptosis (sagging). Larger breasts and breasts with more ptosis tend to have less overall sensitivity.
