If you have someone who has is willing to pee for you and they do so say 15 minutes before the test, to keep it at temp would the bottle actually need to be touching your skin? I ask because I have a pair of underwear that are designed to carry things like this. There is a pocket in the front. But there is a barrier, the bottle would between my legs, but not touching my skin. Is my best bet to tape it to my taint somehow haha? Don't really want to put it in there with a pad because it will surely overheat.
