This is not my own advice, and I don't want credit for it. But I did find it amazingly helpful, especially after trying to hide an unsightly bulge in a miniskirt. xDDD This is Mizuno Tenchi's work from cosplay.com.
Well, here's one issue that comes up a lot. How a guy can hide things
'down there'. There have been links to a few different ways to do it,
but I'm not partial to any of those methods myself. So, I'll try and
explain things for those who want to know.
Warning: I'm going to be blunt and a bit graphic, so if you don't wanna
read it, stop now. I can't really explain and be delicate about it,
though. Fair warning has been given.
Well... first suggestion is to shave as much hair as possible from
around the sac. It's a good idea to at least trim all the hair above it
too. If the hair is too long, it can poke through panties, and that's
not a good look. Less hair also makes it less painful if you decide to
use tape.
The hardest part about everything, though, is the actual 'tuck'. Your
testicles came down when you went through puberty. The goal is to try
and put them back up there. Lay down on your back, and gently push them
into your body and up. You'll need to spend a lot of time prodding and
trying to find where they go, but once you do, they'll sort of 'pop
in'. Don't force this. It shouldn't hurt too much. When you're laying
back, they should stay in fairly well.
Once you get the hang of that, there are a few ways to keep everything
in. My preffered method is to pull all of the loose skin from the sac
towards my rear, and try and stretch it so there's no slack. That way
there's no space for the testicles to pop into.
A firm control panty or girdle can do the job, if you just do that and
push your penis back. For skimpier stuff, though, and when you can't
wear something that bulky, tape works and can be worn with really
skimpy bikini panties, etc.
You can then pull tape from your front, across the sac, and tight to
your cheeks. Use clear medical tape with some stretch. You want the
stretch. Trust me. And it needs to hold well, since this tape will get
pulled at a lot. You can even use the bathroom with this setup, you'll
just have to sit down. Your penis will be pulled downwards a bit if you
get aroused, though, so no fun in the hotel room with the tape still
on. Not something I'd do anyways. Then just tuck your penis back
between your legs, and pull on a tight-fitting pair of panties. I used
to try really stretchy panties thinking they'd hold stuff in better.
Silly me. It's better to get something non-stretchy, and everything
should stay in place fine. You can use tape if you like too, just kind
of wrap it around the shaft and pull it back towards the cheeks too.
Try and keep tape off the head, and only put the tape on when you're
soft, or it won't hold. You can sit down and use the bathroom like this
too, but you'll have to wipe off.
Well, whatever you need to do, getting the balls out of the way is the
most difficult part at first. After that, you can use this method, or a
few other ones to tape with. Once you get the hang of it, it's easy to
do, and comfortable for long periods of time.
I also figured out another way that works pretty well. Just use a
pantiliner (the really thin ones with wings) in whatever panties you
wear, and it helps smooth things out and keep things in better. They're
not that expensive, and... well... for those of you who get a bit...
aroused and "leaking" (I shouldn't need to explain that one, but it can
be either from what you're wearing or whatever sort of attention you're
getting), it keeps things a bit drier and makes for easier cleanup.
