Ball stretching

Hi guys.
I'm interested in ball stretching. They already hang pretty low but I love the feel of them when they really swing ;)
But I'm concerned about possible dangers. Iv read that stretching even a little could cause you to go sterile? I really want kids so that's an absolute no no.
Is there any truth in this or is it just an internet theory?
Thanks

I'm interested in this too, Even though I'm getting on a bit! my balls are quite tight and always have been, I'd love to have them hang low and so would my OH as she likes the idea of them slapping her pussy.

Personnaly I wouldn't try it. You could cause a vericocele or worse if you are not careful, if they don't hang low they don't hang low!!

If you do try it, be careful the old crown jewels are very precious :-)

They are precious, very precious. Once iv had my fill of kids then I will def be doing it, nice n slow mind but will do it. Just wondered if it was possible to do before/during kids.
Think I'll just play safe until I have some sprogs lol
