Microwavable Compress - use for warmup

I’ve been sick recently and used a microwavable compress to help ease my pain. I noticed it held in the heat for quiet sometime (around 20-30 minutes). I think this could be useful for warmup. It retains the heat so you get a consistent warmup. Just something I wanted to share with everyone.

Is this a product we can buy and if so, what is the name?

I bought a Thermipaq (www.thermipaq.com ) at Wal-mart. I use it wrapped around the tube when pumping. It works well for that purpose; I would imagine it would also work well for direct heating.

I fill a cup with warm water and stick my cock in as a warm up. I do this to begin, between stretching and jeqling and again at the end. I have not done any research but I assumed that was a good warmup. If the wraps stay hot for 20-30 min that is great.
