Something I haven’t seen mentioned here is the fact that sweat acts as a lubricant between the skin of your torso and upper-inner arm preventing chapping with increased skin-on-skin contact movement.
Yes, the sweat keeps you cool and the smell attracts others with different immune system.
Can you develop the part where the smell attracts people?
One (old) piece of advice I heard.
Your pocket handkerchief. Rub it on your balls. Then put it back in your breast pocket.
You will get more attention from the girls.
Pheromones are real and powerful.
Hormones are weird. We can smell things we don’t think we can smell.
When she’s turned on. I can smell it. But it isn’t really a smell. Like I’m unconsciously smelling it and then my unconsciousness taps my consciousness on the shoulder.
Supposedly the smell was something prehistoric people would flaunt. Mating in a lot of species is odor-based, and at one time, we were no exception. They did an experiment in an episode of a science program called Brink where they made a pheromone system that could be used to detect how related you were to a potential mate and found it successful. For us, they say, it just happens to gather in our armpits.
Whatever prehistoric people thought, nowadays we seem to dislike body odor and tend to favor filling the room with a mist of Old Spice.
