Can I Use magnesium spray?

I read somewhere magnesium is really beneficial , Is it okay to use magnesium spray (the one with chloride)

Been using it for a few weeks ,
I try to avoid contact on the testicles since it cause some kind of chlorine rash

2-3 sprays on the glans seem to have no immediate side effect

But practically is this beneficial?
Does spraying magnesium spray which contains chloride on the glans dangerous thing or beneficial thing to do,?

Thank you for reading

What are you using it for?

I had read that magnesium chloride was helpful for softening scar tissue, and I used some on my shaft, including the glans. I felt a very mild burn, but I was only using a small amount mixed with some other stuff.

I am using it to resensitive some part of the shaft .
I think i might have tightened the hanger too tightly , some part of the right shaft is not numb but less sensitive than the left part of shaft

Hoping magnesium chloride can speed up my nerve healing process

I think we shld be careful when using ,because my testicle literally got chloride rash ,
I made dumb mistake of spraying 2 to 3 sprays directly on the ball ,thinking it can increase sperm output

Though spraying it on the glans did not cause discomfort which is weird , i thought glans r more sensitive than ballsack
