I read the substitution guideline, it's just that when I tried it with 2 visine bottles, my temp would stabilize at 93 degrees and wouldn't go any higher. I was thinking the condom would absorb the heat from my body better right?


Hmmm I'm considering the ziplock method you mentioned, and I have some of those back/stomache pads already at home. How hot will it make the piss that I'm using? Do the drug testing cups already have temperature strips on them so I can tell how hot/cold my piss is?
