stretching

I feel like my scrotum is tighter than ever. Too much caffeine? I am on TRT and my balls have definitely shrunk a little from that too. I've never tried any sort of stretcher, weights, etc. I saw a pic from @Jblocked with a ball weight on. Does anyone have experience with ball...

Hello all, Does anyone here have experience with the looker02? I've bought one a few months ago from this site. The bulb on the insert seems to be a bit too large for me. Can someone give any advice on how to make it fit? Should I try some stretching? How would be best? i'm not into stretching...
