I recently purchased a vacuum hanging cup from peak male physique and have been hanging for about a month and a half now… I decided to play it safe and start at 50 g weight I got off eBay and increased by 50 g at a time once I felt safe doing so. I am now at the point where I am ready to try heavier weight (a little 2lb dumbell from when I was a kid) but I cannot keep the weight from pulling the vacuum cup off. Any suggestions on how to keep the vacuum cup attached to my penis with heavier weight? I already tried getting a good seal first, then adding the weight…it stayed on for maybe 2 minutes before breaking the seal and pulling the cup off
