Pimple thing from pumping?

About a year ago, while pumping on a regular basis, I developed some kind of pimple thing on the skin of the underside of my shaft sorta near the base. It would be at it’s biggest after pumping, and maybe shrink a little if I gave it a few days off. It eventually felt like it had a somewhat hard internal feel if I squeezed it.

Eventually I took a sterile needle and lanced it and squeezed out the inner fluid. It also bled a little, but after a while it was mostly gone.

Back to pumping regularly again, I developed another one of these “pimples” very close to where last years was. (underside of the shaft near the base)

What are these called? And what can I do about this new one? Is lancing it a viable option?

And how can I prevent it from happening yet again in the future?

Differential Diagnosis:

1. Folliculitis - infected hair follicle “ingrown hair”

2. Sebaceous cyst(fluid filled sack) or inflammation “itis” of Sebaceous gland

The Sebaceous glands can appear as salmon colored dots on scrotal skin and in mouth on buccal mucosa. They are then called Fordycle

Thanks, yea the (sebaceous) cyst seems to be the best match from what I’m seeing on Google.

Does anyone else here get these on the mid to lower part of your shaft as a result of pumping?

(These are definitely not the little bumps that surround the glans head)

I guess taking a break from pumping is the safest way to make it go away? (pumping seems to make it temporarily grow and perpetuate it)

Or is lancing it properly/safely a viable way to get rid of it?

But most importantly, how can they be prevented in the first place?

Lancing it is(probably) not recommended.

That being said, I have had success popping one that was at the very base of my shaft that was preventing me from wanting to pump and I was able to pump the next day after popping without complication.
