I kinda made a funky diy thing that I use sometimes. You might be able to make one if you want. Though imo it feels better with using suction, which I think may possibly effect your junk if you do it often (it’s basically some kind of pumping). It can also kinda hurt and make your junk swollen, so just be wary, and unsuction it if it hurts too much.

I got a cheap packer a long time ago, but after I concluded I was never going to use it for actually packing I went ahead and dug a hole through the base of it, and tried to make it go as far into the shaft as I could get it. I can still use it to pack if I ever want to, but I just can’t like resell it or anything now lol, and personally I wouldn’t want to do something like this to an expensive packer.

I then got these things. It may say they’re unavailable, but you should be able to find the same sort of things elsewhere on amazon or other online stores. In the pic, the long one that is the second from the right goes into the hole in the packer. It’s a good size to fit your junk into the open end of. Then if you squeeze it to use suction then you can pull a bit at the packer shaft and it’ll tug at your junk like your jerking off.

I don’t really use this method often though, because the suction comes undone kinda easily when you’re pulling at it repeatedly lol.

If you’re using a cheap packer it might not look super realistic, but you can try painting the packer to look more realistic. They may make like printed condoms too that may look more real, or you could see if putting a regular condom on it might make it feel or look a little more real.
