I love to freeball with a cockring around my balls and top of shaft. I would say I do it for the following reasons:
-Makes my cock outline quite visible especially my corona
-Insecurities/Attention/Exhibitionism
-Keeps things in a nice package away from my body, so nothing clings
I recently walked past two ladies at work, smiled and kept ahead as one lady started whispering in her friend's ear. As I made my way up the stairwell, I overheard the other lady giggling the response, "We have also seen it...it's very big"
A bit risky for sure, but I kinda feel like one of the hot guys as work.
