Sebacious cyst on my penis. What should I do about it?

[Imperio05]

I'm a 20 years old male I never had sex but I masturbate frequently. Around 1 year ago a huge pus filled pimple appeared on my penis. I popped it and another one appeared on the same area after a month and I popped it too. But now another huge pimple appeared, so this time I went to a doctor and ge told me that it's a sebacious cyst and there's no need to worry. He gave me some medications and also a gel to apply on it. So I took the medications and decided not to pop it. But now it became hard inside and a whitish line grew from that hardend cyst. It is painless. Little darker in colour and appears like a lump. I don't think it is a STD as I never had sex before.
Is it really a sebacious cyst or something else? What should it do about it?

I've had a couple of these in my life.  I never was given any medication for it, don't really understand that.  Once a doctor just flicked the whole thing off and walked away.  That was the end of that one.  Once I was just told to soak it with a washrag soaked in hot water repeatedly and that took care of that one.  When you do get rid of it, try to keep the area cleaned, this is a sweat cyst basically, but it's nothing to worry about and they do go away.  Peace.

Don't worry about it hardening, that's just the body's way of encapsulating it so it will ultimately go away. You removing it is not what should be done.  Here's a reference about the topic, it's very informative:

One of the interesting parts of the writeup is that if "part of the sac wall remains on the skin" the cyst might form again. That seems to explain why your home attempts to remove it were not effective in the  long run.

I had one of these in an earlobe once, just a hard little lump. I never tried to do anything to it, because it didn't look funny or bother me, but it was there. Then one day months after I noticed it, I idly felt my earlobe and the cyst was gone. Probably my body simply absorbed it. If your cyst bothers you a lot, you could ask the doc to remove it, but it might take care of itself over time.
