Packer riding up

Hello all!!

So I recently got my first packer, (axolom thinker with the boxers for it,) and I’ve been trying to wear it in public. However, whenever I walk, I can feel it coming loose/riding up on my anatomy. Are there any tips for keeping it in place?? I’ve never packed before, so I also don’t know how to position it 😭😭 I just pack downwards with it.
