Can an ingrown hair or white pimple disappear upon a slight touch?

[bartaMan]

This morning I found a single, painless white bump where no man wants to find one!  I do have HPV and do routine self checks for outbreaks.

This pimple was white, raised, and painless.  When I went to touch it very lightly with my fingertip to see if it was painful to touch, it literally disappeared before my eyes!  No puss came out, it just... appeared to disappear.

Now the spot where it was is still painless, but now a pink/red color.  Was this an ingrown hair or inflamed gland?  No STD symptoms I've researched has behaved like this.

One thing has changed in my active life, and that's I've joined a health club and have been using community whirlpools/hot tubs, and a steam sauna from time to time.  I've noticed a slight increase in folliculits from the chest down.

Thanks in advance for your helpful answers!
