Lump on Lower Shaft of the Penis !

Yesterday I noticed this lump on the lower shaft of the penis. I masturbate quite often but I aint sexually active. The lump is kinda reddish purple and itches . As Far as I searched on google it says that "lymphocele" ! Is there anyone who might help me out ? Is that something serious ? ADVISES are always appreciated . rha

Can you get a closer clear photo of the lump ..
When you have been masturbating recently do you use something as a Lube, or perhaps apply something to your penile skin before, during or after?
What age are you?
As you are not sexually active - state how long ago if you previously were? - it is very unlikely that this is something serious …

M in long distance relationship so last time i had sex was arnd 2-months ago
