I'm 20 yrs old, I'm about 5'9 , 210 , my penis shrivels up when Im sitting down, when I'm running, playing basketball and when I got into a fight it did that also and sometimes it'll stay like that for long periods of time even when I'm not sitting, running, playing, or fighting, what is the reason for this? High blood pressure? Might I be overweight? What are all the reasons?
Also my penis when hard is about 6.1 long n 5 wide, is that a good normal size? Average?
Changes in body temperture causes our penis to strink back/draw up. When you're hot and sweaty, or jumping into a cold shower/pool, or just out in the cold. If you're over weight with a belly, well it's for sure to look smaller than it is. Can anything be done about it? No. I guess you can pull at it to get the blood circulating. That will make it a tiny bit erect, just enough to give it some volume. Hey, we all hate it when things look smaller than normal, but that being said, everything sounds normal.
