I have not been with a lot of women but have viewed many on the internet of course. My question concerns the inner lips of a woman's pussy. When younger they do not flap or protrude obviously. Are the long lips that extend out directly related to friction and contact? Meaning the more sex or insertions that tug and pull cause them to stretch over time and remain that way. Or....is it inevitable with all women as they age and some just have more flesh there than other women? Thanks for the input.
