penis bump

I have this new bump on the left lower/mid side of my penis shaft and I am just worried about what it is. It is not exactly a raised lump that you can feel, but feels more like it is under the skin. If anyone could help me with telling me what they think it is I would really appreciate it.

I have uploaded a few photos of it and i hope you can see the bump i'm talking about even though it is hard to see through photos. 

I can see the bump, but sorry to say I can't identify what it might be. In your position, I wouldn't be worried and would just wait and see if it disappears or develops.

What should I do if it doesn’t go away ? Does it look dangerous to you at all? Btw I’m 22 and a virgin so it can’t be std related. 

What would you do if it was on your forearm? It's no different really!

But surely these type of lumps wouldn’t just come on the penis for no reason right ? My head keeps telling me it’s something bad and I get anxious with new things on my penis. And I don’t really want to get it checked by a doctor coz it’s embarresing.

Does anyone else know what they think this is ?
