White pimple/bump comes and goes...?

[bartaMan]

I have HPV and do routine self checks for outbreaks.  Monday morning I found a single, painless white bump on the top of the shaft closer to the base.  

This pimple was white, raised, and painless, fairly noticeable.  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.

The spot where it was at was painless, but a pink/red color for the next day.  By Wednesday you couldn't tell anything was amiss.

This morning there was a very small but noticeable white bump in the same place, with a tiny black dot in the middle, maybe a little sensitive to the touch.  This looked more like a pimple or inflamed/ingrown hair follicle.  I take my shower, get out, dry off, and no sign of the white bump at all!

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.

Any ideas...?

Hi from what you described are normal inflamed folicles and pimples that men get. Herpes are blisters and are not white or black and HPV are warts. Between all of these theres not much else it could be.

I've had ingrown hairs, and still suffer from acne/bacne.  My acne gets more severe, some cystic, and takes a while to clear up.

This whole "disappear right before my eyes" trick never happened to me before, so it kind of freaked me out.  Maybe normal for the rest of you, but not for me!
