Infrared therapy socks, post workout wear?

Yesterday I had a wonderful experience of post jelqing flaccid hang (first time in my 6 months of PE). I was also wearing long johns. So I suspect that the warm heat from long johns might have been keeping my unit rather warm, and hence the nice hang.

I did some search and found this site:

(infrared therapy socks: the smaller clothing they have)

Usage:
FIR therapy socks can be used for increasing blood circulation and relieving pain and swelling in the feet, toe or ankle area. In particular, it is effective for foot raynauds disease, cold feet, feet numbness, ankle sprains, swelling feet, tired feet, tarsal tunnel syndrome and foot injuries, and for symptoms caused by diabetics, etc. Far infrared light has also been found to inhibit bacterial growth, prevent athlete’s foot and reduce the chance of infection.

Do you think this would be a good post PE workout wear for a couple hours?

Or, Infrared Therapy Briefs

I wonder if these underwear would help guys with Pudendal or any other genital nerve damage? Infrared is said to help regenerate nerves. They may be beneficial.
