dorsal and lateral strectching

Just a question that popped into my mind after examining the stretch mark serving as evidence of my roughly 0.5in gains. My stretch mark appears only dorsally on my dick and not at all laterally. Does anyone have strecth marks that appear the entire circumference of the penis? Most of my gains came from manual stretching (V’s and general tugs) and hanging straight down. I would assume that one who hangs over the shoulder, does dld blasters, or manually stretches toward the belly button would experience the same stretch marks laterally. Or am I just plain wrong?

My emerging stretch mark goes about 2/3 of the way around; it’s most prominent on the sides, however… by prominent I mean it looks wider and paler.
