Discreet Warm-Up and Warm-Down Method!
This is a great method I discovered for those of us who:
1) Need to be in their room, alone, the whole time while warming up.
2) Do not want to or cannot use a microwave for the rice sock or heat pad.
3) Cannot keep going the sink to wet a towl.
This method requires a mug or cup. Sure you have to fill it in the sink, but it stays HOT and it is discreet. No one will question you filling a glass with water! It is totally fail-safe!
I attached an illustration to help demonstrate why this works so well. Since the cup is suctioned horizontally to your crotch, with the base resting on a side of the desk or bedpost or wall, your hands are FREE to play games or use a laptop. That is the best part. And it does not get your testes hot so you do not kill of those precious sperm!
All it takes is a cup and a vertical surface. Try it once, you will see that with ten seconds of getting the hang of it, not a drop will spill because a great suction forms between the container and your body. See the image for clarification.
