Lump on penis

I am a 17 year old male, I have found this lump on the shaft of my penis a few weeks ago and didnt think anything of it until it started to grow and turn purple, I am not sexually active, any help?

To be honest mate it looks like a pimple wait until it comes to a full head and then bst it then bathe it with some antiseptic and keep it dry.

 

I have similar problem, I found lumps in my scroto as well, and I feel itchy skin in my whole body since 2 months ago. Caol, did you find out anything? Thans!!

I have the exact same thing but with swollen lymph nodes in my neck ,can anyone help?
