Warm Up Question

Hi I’m new to PE been doing it for three weeks been doing good had some red dots the first few times so I decreased my grip and been doing good since .

So my question is everyone says they use a warm towel or rice bag to warm up, I have been using a tall glass of very warm water ( fill the glass up put my dick in and hold it tight to my pelvis keeping the water in).

Does this sound like a good way to warm up or should I switch to a rice bag.

Its fine as long as the heat doesn’t get dissipated quickly.

Awesome thanks for the input.

So I recently bought a rice bag for my warm ups and I must say it is way better then what I was doing I can do it anywhere on the couch bed where ever and less mess and way better heat.

Yes, rice bag/sock is the way to go. After my warm up I cover it with clothing or a folded up towel, and it’s still hot enough for my warm down.
