After jacking off.
Sorry if this has been asked before.I couldn’t really find much on it, but lets say my flaccid is 4 1/2 inches and I jack off, for the rest of the day it goes to like 3 1/2 inches.is it because I jack off that I lose blood pressure in there. I noticed if I don’t jack off for a whole week then it stays at 4 1/2 all the time, but once I do it then for the rest of the day it’s smaller and thinner.
