Panty-sniffing, as we call it, harkens back to our more primal nature for our species. Whether or not we as a species "evolved" or were just more primal going back in history we would be attuned to scents way better than today. Plus, and please, we all know the benefits of modern hygiene so the teenagers in here and germ-freaks need to move as the adults in here will get it, the role of stink had its place in humanity. Especially for breeding. Anyone how knows anything about animals knows that breeding is about scent as much as any act of copulation. The same goes for humanity.
When we take in a whiff of musk/fish we know were it comes from not to mention the same for the woman's butthole. Going back in time when there was little to no shaving and hygiene was not as dominant or certainly not "down there" then any sexual activity was about the STINK as much as the act. This translates into "panty sniffing" in 2019. The olfactory part of our existence as a species has been conditioned to see STINK as abnormal when, in fact, it is the most normal part of any intimate relations between a man and a woman or two women.
Say what you will and even with the humor of this statement there are times that women should be hairy + smelly to dive in and feast
It is who we are as a species
I get that smooth and pristine is normal in this day and age (look at newgirl16 for proof of the most perfect smooth ever) but for many of us the craving for hairy and stink = 100% normal. My wife does not shave any pubic and/or butt hair and I can smell her ten feet away when she is wet-that is how I flat out love it. She knows that I masturbate to her creamed and dirty things and loves it. Just be what you like and love it is the key.
