its so uncomfortable to wear all day when i sit down at work on a computer. if i can sleep on my back all night, it shouldnt be a safety concern. so, wont wearing it over night make it easier??? anybody slept in theirs before?
You should really look into using the search feature. Pretty much all of your past threads could be answered quickly there.
But in case you don't want to, NEVER use an extender while sleeping. If something starts going wrong, you're not awake to take the extender off...unless of course you want to render your penis useless.
