I think hairy men can be sexy if the hair is kept under control with some primping (not freakish primping like…braiding armpit hairs or the chest hair confined within a perfect 6x6 inch square in the middle of the chest).
But I do find men with extremely dense, dark, curly, crinkly, dense, coarse, black, long, thick curly hairs ALL over the chest AND back and when their arms are hanging at their side casually it’s like they’re hiding a piece of toupee in their pits disturbing.
It’s time to do some primping when one has visible body hair on their kneecaps, behind the knees, on the shoulders, in the crook of the elbow, and in the back of the elbows.
But if you’re not that hairy and your girlfriend wants you to shave your pits, that’s kind of strange. It’s effeminate, imho.
