Thanks, I have never personally been with anything but pink lips, the thought of darker lips intrigues me
Same reason some people have light nipples and some people have dark. And why some people tan and others burn.
Well, my guy [in his mid 50's] confidently says that darker pussys have had children. He has been with many and he did not know that I had never had a child when we first made love. He was surprized and said "Your pussies pink, you don't have any kids------------amazed me." We watch porn on occasion and now we both watch for the color of the puss.
It's genetic, but in the women with lighter to medium colored lips, they sometimes get a little darker during arousal due to increased blood flow.
