White dome shaped lump/spot on penis

Hi, 

I discovered this lump on my penis a few days ago. It is painless, non itchy and very hard to see in most lighting (shows up well on picture attached) it’s that small that I can’t even tell if it’s flat or raised.

It doesn’t have many characteristics of a genital wart but I don’t know what else it could be!! 

Anybody had similar experiences? 

Yes very I’m lost

To upload photos:

Some phones can upload (you have to use desktop mode), but others don't. The scenery icon is the one you need (but the icons don't appear on either of my phones or tablets). 

Alternatively:

First transfer the photos to a computer. In the computer browser, log in to Patient.info and hit reply in this thread. Click on the 4th icon on the right above the reply box and you can upload photos from there.
