my penis is like, tight, just proximal of my circumcision scar. i'm 24, and i just noticed this. when i get an erection, everything fills in but this region fills in last. when i'm fully erect it's normal as it always has been. in my mind, it's like the skin there is squeezing the blood out. this has happened as like, a weird thing when i've been really cold or something, maybe like 5 times in my life total, but has happened every time i've gotten an erection the past two days.
i have no clue what to even search for, because everything on google returns stuff for "erectile dysfunction" and "peyronie's", and people talking about how to make their penises bigger and such.
