What is this large lump on the shaft of the penis?

I am 20 years old male. it's been a very long time since I've noticed this lump on my penis, about 4 or 5 years. I've ignored it because I thought it was nothing to be concerned of but I've started to notice that the size has been increasing. There's no pain when I touch it or skeeze it, I am also able to move it around. But nevertheless I am very concerned to what it is. I am hoping it can be solved here because I don't want to go for check up as I am not comfortable with that.

If it helps, here some images to give you a better idea:

If anyone has any idea what this might be, what has caused it, if it is dangerous or how it can be treated then please respond ASAP!

Thanks.

It may be a harmless cyst, but to have it treated you will need to go to a doctor.

I forgot to upload an image, so to give you a clearer idea on what it looks like:

Hi Yes like pep said its a sebaceous cyst now if its soft and with a clean needle past it through and get the puss out till it bleeds, run some Germoline into it should gone by the next day unless it comes back if just do the same.

Hi, thanks for your answer. I dont think its soft, when I touch it and squeeze at it, it feels like pretty solid. When you say soft do you mean soft like a spot? 

Hi M Do see your doctor then he/she will cut it out for you all very simple to have done OK

OK thanks but I dont know, I am not nervous but I do feel uncomfortable about other seeing and touching

You should never let anxiety or discomfort stop you from dealing with any health issue you have.  I do personally know that this is difficult showing your penis to someone else - but all medical professionals see dozens of male and female genitalia every week - all they want to do is sort people's medical issues for them.

In terms of cause, I would suggest this is often caused by accidentally or deliberately putting severe pressure on an area of the penis.  Many men in particular cultural and ethnic groups practice what is described as 'natural penis enhancement' known as Jelqing - this places considerable pressure within the penis, and, as I know from personal experience, it is all too easy to injure your penis in several different ways, one of which is to create a cyst.  For those who use the Jelq, you essentially need to learn how not to injure yourself ..... perhaps you got your injury in some other way .....

Hi M, Then its time to man it up my man, and not very good for your sex life.

Try to overcome your discomfort. We all eventually need to trust professionals in the medical system to handle our genitals when necessary. I've had vasectomy, urinary catheters, and urology examinations and have always found the professionals are discrete, non-judgmental and caring of my feelings - emotional and physical. Have courage!

Haha, I've never practiced any penis enlargements. This has cyst has been on my penis for a very long time, I don't really know how it happened. But thanks.

Hi, I guess I should do that, thanks.

Thank you, I'll go and see what happens. Hopefully I can request for a male doctor as I feel more comfortable with dealing with the same sex.

hey! same happening with me. Did you find the cure or treatement or anything that can help me? please

I’ve got the same lump on almost the exact same spot. It feels like super hard cartilage under the skin. I’m 40 and its been there as long as I can remember, pretty much my whole life.
Ive been thinking more and more about getting it removed. Did you get it removed?
I’m not even sure what I should say it is to the doctor. I thought I was the only one who had this.

if its hard structure and even moveable but no itching no discomfort no bleeding then it may be smegmolith. you can search that word on google. basically it is a collection of smegma and after some time it gets hard and become stone like structure. smegma is non cancerous and its not a very serious or life threating problem.

did you ever figure out what this was because mine looks the SAME as this and i have no idea what it is

Did you ever figure it out man??? I just noticed I have a lump on my penis same spot same size
