Okay so often times I have to run in daily life (busses, sports, and other stuff) so how can I keep my cock from trying to escape? I have a fear that one day I will be running like hell after the bus and my dick will slide down my leg. What brand of boxer breifs have a good pouch? I can't shell out that much money for tranzwear of any kind of really fancy boxers.
I use a packer holder with my stp and I have no worries about falling out of place. Just simple piece of elastic is all mine is and works like a charm.
You could always use a jock strap: they're designed for supporting and keeping things in place (i.e. basically exactly what you're looking for). You can order them online as well and Jockstrap Central always seems to have some kind of sale going, plus you get coupon codes with your orders (at least, I did with my first one -- haven't ordered again yet). They also have several inexpensive jocks, swimmer jocks...all kinds of jocks.
Another option you can consider is a cock sock which you can make yourself pretty easily. I know there's instructions somewhere or another online.
If you want as little movement as possible, I'd highly recommend the jocks. You can wear them under boxer briefs or whatever else as well if you'd like. Keeps the packer nice and secured however you wish to arrange it, so no need for adjusting either unless you want to.
I'm going to second Noah. A jock strap will probably be your best bet in terms of wanting to run around and be secure. Tight underwear really will not be the singular best option, but more like tight underwear in combination with something like a jock. I use a simple elastic harness and while it has held me in place for a short bout of running, I wouldn't trust it doing sports or going on a jog. Maybe in combo with tight briefs, but I hate briefs.
So, yeah. Try something like a jock strap and try wearing snug whatever-you-wear-under-there.
If you have an old rag or tshirt you can also sew it inside your underwear (if you were briefs/boxer briefs) so that the new patch goes against your body and your packer sits inside the pocket that is now created.
I just cut a smallish hole in the front part of some underwear of mine that I didnt wear so much any more. Then I put the actual penis through the hole, and the balls would just stay in the underwear :P I wear some boxer brief over the top of that and then position the packer the way I want it. It cant fall out, cause the hole in the front of the underwear is definitely not big enough for the balls to go through. I didnt know where to get a jock strap or harness or anything from, so this works fine for me! 8)
I just use a waistband with a slit in it works like a charm.
And its free, all you need is some scissors and an older pair of undies.
I use a jockstrap (nice and cheap) or put in in the 'pocket' of boxer briefs. Both work well but sometimes the thought of it popping out of the briefs and tumbling down my leg is a lil frightening! lol-i prefer the jock. you can also wear it (jock) under regular boxers, if you are a boxer guy.
yeah im a boxer guy so i use a jockstrap and it works great!
i used to just wear tight boxer briefs but they tend to loosen during the day and then i need to readjust way too often....so i made a cock sock from the sock piece of a pair of nylon stockings and two safety pins attaching the stocking to the inside of my boxers. feels much nicer against the skin than a regular sock and everything stays in place.
