Cumming while balls are tied?

[jared7577768]

I've been wanting to try this, but I'm afraid I might hurt myself. Your balls are supposed to retract into your body when you cum, right? But I've seen vids of cumming while the balls are tied up or restrained so thaey couldn't retract...does anyone have any info about this?

It depends on how far your balls retract during ejaculation. In my case, it doesn't feel nice when my balls are restrained too much while cumming. A mild grope however, hmmm. This is the only time I came with a rubber band around the balls:

I don't think it does harm you, I do this alot and haven't noticed anything negative in it.
