I’ve been using unique-heat thermo flex flax wrap for warming up. My question is should I just wrap that around my penis? Or around cock and balls? I’m not sure because too much heat around the balls is bad for sperm production right?
Also when warming up with a hot wash cloth, just wrap around the penis only? Or around the whole scrotum area, cock, and balls?
Any other methods or tips would be great too. Thanks!
