I was thinking about that.
I might have kind the same thing but I am a hypochondriac and I know that when I am thinking about I think to have a mild pain/discomfort as you said. When I am not thinking about it I don’t have it.
I have erections, morning wood, etc. No spots, pain when touching etc
Still think that this is in my head. Big time.
All we have is a “penis ache” and that can be normal after sex or masturbation. But we think too much about it and that is it.
