I just discovered this yesterday.
For as long as I've known I've jacked off 3-4 times a day and never understood the appeal of edging. This week though I had to hold off in order to a sperm analysis, it's been really hard (pun intended). Yesterday I was so tempted to beat off first thing in the morning and I even got started but I was able to stop myself and go to the gym. Holy shit that workout hit different. I had way more drive to push myself harder mostly because the really hard lifts felt pleasurable. I'm already big when soft, but I had a slight chub the whole time and I noticed by bulge caught a few stray eyeballs, the exhibitionist in me was pleased.
I tried it again today and it works amazing. It's the best pre-workout I've ever tried.
I also sometimes wear a cockring to the gym. It keeps the package together and helps my ego when checking my progress in the mirror. I have an adjustable leather snap button one that I wear as a bracelet when it's not on my cock. Buddy in the lockerroom did a double take one day when he saw me snap it out of my underwear and put it on my wrist before going to the showers. lol. I love this style of cockring because it is, in my opinion, the most comfortable. I also think it's so fucking fun to give a new trick the orders to take it off my wrist and put it on my cock. Just watching the gears turn in their head as they realize what it was for all along.
