So I've had an STP packer for a few months now and like to wear it as often as is feasible. I have gotten a couple pairs of boxers meant to hold it in place but my job is pretty active and I find that the STP just doesn't stay put when I have to move around and lift things, step over obstacles while walking in the woods, etc. I also will be doing a lot of camping and hiking for my job so I really want to be able to wear my STP so that I can keep my masculine image if I need to pee while hiking a trail or whatnot. Anybody have any advice on STP harnesses that do well with an active-type lifestyle? Thanks, Casey (he/him)
I've heard that jockstraps are really good because they have a pouch at the front used to hole a cup but you can cut out a hole and put the STP through and then put boxer briefs/boxers on top? There are quite a few homemade underwear suggestions on YouTube as well as reviews of packing underwear so I'd check there if you need ideas.
When I wore a packer, I just used a jockstrap to hold it in place while I was working. I never had an STP though. Jockstraps are usually pretty cheap though, so you could always test that before moving to other solutions that are more pricy.
