Well wearing diapers all the time doesn't really screw with your body. Hell getting a hole poked in your ears screws with your body more and that's a normal activity now.I suggest it because he's doing the typical newb thing. That is, signing up and posting a thread asking whether he should purposely screw with his body. I just don't want people making hasty decisions that they could seriously regret.
Umm.... I think you got mixed up at the end there.There has been NO proof ever that wearing 24/7 will make you incontinent. I have no idea why people think it will when there's no proof of it at all. In fact just the opposite is true, what do people wear up till there two to 3 years old, diapers. How often do they wear them, 24/7. Can they be potty trained, of course they can't.
This would only happen if you released at the first fealing of needing to go and if you consciously tried to relax your sphincter muscles. If you hold it for a normal amount of time and void just like you would if you were using the toilet then there won't be any physical changes. But after a while your brain will get used to going while you have clothes on so if you decide to stop wearing then it may take a little "training" to get back to normal.It would relax his sphincter and possibly make it hard for him to hold himself, depending on how long he uses them..
Go for it. It'll be expensive, but since you already wear to bed, and it's highly practical for long-distance driving (sometimes encouraged), there's really no reason not to. As said before, you'd only have a few hours, if that, to go with underwear, but you could choose to switch between them anyways.
Remember that going 24/7 is one of the only ways to train yourself to be incontinent. It is NOT a guarantee that you will become incontinent just because of that fact. If you want to retain your control, you will!
Besides, you're on this forum, meaning there's a good chance you'd enjoy it anyways.
