I have been reading about it quite a lot here. I personally think armpit fetish is at the top at the moment, correct me if I'm wrong. I want to know what's the psychology behind it. What do people feel and think when they see a candid armpit.
From my personal experience, I have noticed the same. Whenever I wear sleeveless in public or even at my office, the attention is slightly more than normal. I do own kurtis with big armholes that reveals major portion of my armpits along with a little side boobs but only if the bra is tight. Also I'm someone who maintains a proper armpit grooming schedule to keep them fresh and feminine.
Don't hit me up directly, we can discuss it in the comments itself.
