It is a medical fact that a woman produces pheromones from her armpits, and I have found that a woman who DOES NOT comply with the "social norm" of shaving/waxing (or whatever else) their armpits actually produce a higher level of pheromones; to the extent that pre and during sex these pheromones are a HUGE aphrodisiac and as a result increase both partners sexual experience.
However, a woman that does shave/ wax etc. actually "hardens" the skin of the armpit, which in turn reduces the release of these natural pheromones.
I actually have a wealth of information on this topic, with actual experiences and "studies" and anyone who is interested can add me as a friend here and I can then share these with you.
I'm admittedly odd in this, but I prefer women who are all natural. Seems like the preference today is to remove every hair on the body, except that on the head. Takes all kinds to make a variety though.
