Strange "Coating" on the pubic hair of the Scrotum?

As you read this, it may seem strange, and it is, which is why i am asking these questions and listing these symptoms. I hope someone can shed some light on this for me, as i am stumped as to what could be happening but am not yet ready to bring it up with my doctor.

Back in March, i shaved my pubic hair off completely to see if it would spice up the sex life of my marriage. She enjoyed it, but the amount of upkeep to prevent chafing was ridiculous so we agreed to just let it grow back.

Once it began to grow back in, the hair on my scrotum (specifically, the hair at the very bottom of the testicle sac) appeared to be "Coated" with what i had first thought was simply skin due to in grown hairs. However, the substance did not scrape off of the hairs when using finger nails in an attempt to clean the hairs off.

I have washed the area thoroughly on a daily basis and there appears to be no improvement. It is not itchy (at least not often, in fact, that is rare) nor is it reddish or irritated in any way. The hairs themselves look almost like they are covered with pasta dust (if that makes any sense) as those hairs appear to be a lighter colour than any other hairs on my body.

Recently, i postulated a theory to my wife that it might be a yeast-like infection because, as weird as it sounds, when i am sweaty or physically active enough to cause that area to become moist, it gives off a very distinctive odour that smells very much like home made pizza dough (which contains yeast, of course).

Does anyone have any sort of clue or direction in which i could be directed to clear this up?
