IR lamp

I want buy IR lamp (150 watt), and I want use IR lamp throughout the routine.

How can i heat the underside of my penis without become blind? :P (i want heat my corpus spongiosum directly)

An infrared heater, rather than a lamp, would keep you from being blinded. I am a little leery of putting such devices close to my body without some sort of EMF canceling tech involved. I am saving my beans for a Clearlight one person FAR infrared sauna. Not only will it help with extending my package (theoretically), but it will help extend my lifespan (scientifically proven). Plus it has EMF cancelling tech built in.

Don’t look directly at the lamp? That’s how I do it.

I have no experience with an IR lamp for this particular use - I use a heating pad for warm up/down and stretching; however…

My first thought is to use some sort of tin foil (or the like) to reflect the light and heat. This should allow you to heat from the top while having the dispersed heat being redirected back up to the underside of your dick giving you complete coverage.
