Occasional hard cyst like bumps on the shaft of my penis.

They seem to just appear sometimes and last a few weeks to a month or two. Usually pretty small ~.5cm but varies.  Always feels like a hard nodule beneath loosely the skin. Skin never really reals or erupts. Never any weeping or discharge. Always seems like it may be focused around a pore or follicle although can’t always tell. Usually very round and can se a dot or hole in the center after awhile. Maybe subcasious cysts or epidermis cyst based on googling.   This last time I tried using a strong antiseptic skin cleanser and had a different reaction. It seemed like the center dot or pore opened up exposing a hard white surface.

Most likely a sebaceous cyst.  They will drain after awhile.  Usually caused by sweat getting trapped down there.  Wash there when you shower.  If it sticks around, a doc can either poke it right off of you or drain it.  You can drain it yourself often by keeping a hot moist towel or something on it for awhile and it should start to drain.  But I'm not a doctor, I've just had them a couple of times and that's what it sounds like.

So who would be the proper doc for this a dermatologist or a urologist?

Really, either is fine. Call both and whoever you get into first and/or is more convenient. Either can treat this.

If it's a sweat cyst, your regular doc or even a good physician's assistant can take care of it.  If it's something more significant, your regular doc can refer you to the right specialist.
