Dear ryan,
I think you might have lichen planus. Check this on Google and select the DermnetNZ page for more information. It’s quite common and not serious in the vast majority of cases, despite the long list of complications/diseases!
Try to see your GP, or better still, a sexual health clinic. Mention that you might have lichen planus penis and see that they check for other features; if the diagnosis is correct they should be able to prescribe a steroid cream. Even without treatment most cases of lichen planus clear spontaneously.
Rgds,
Adhari.
