wish my balls werent there

my balls go inside when I am about to shoot a load. They literally disappear and don't come back till 3 or 4 minutes after I cum. Not sure if this is normal but i'm always glad when they come back.
this pic shows one gone and the other slowly coming back after a huge load

I love pushing mine up hurts for a while then goes off but does feel good when i cum like it

i wasn't aware that you could do this....and im never going to try...

Mine go up easily and tend to do so every time I cum. I'd like to be able to get them to stay when I want, but cannot. I'm not a ball fan, so I like tight, empty-looking sacks. and would like mine to pass as such when I want.

This has always bugged me as I find it very uncomfortable when it happens. My balls don't go up inside either easily or willingly and its quite painfull when it happens forcefully during sex. For many years I have used a soft elastic hair band behind my balls to prevent this happening, although I don't like the sensation of a true 'cockring'...so guaging the elastic to be tight enough to prevent 'ball loss' but loose enough for comfort and function can be difficult!
