Girthier at lower erection level
So I remember a post from sparkyx who said he believed this meant the tunica had a greater amount of elastin compared to other guys.
I thought it would make sense to consider this:
The inner layer (circular) can expand more than what we see at full erection, so is it possible the outer longitudinal layer prevent from being girthier fully erect by compressing it?
In this case would tunica stretches help gain girth instead of length?
