| ive been having sex since i was 17 and im 25 now. since that time i have noticed at least a 2 inch size increase. sometimes when i have sex my penis stays rock hard and my girlfriend notices it. even after i nut and i continue to have sex and nut about 8 more times before i rest. other times my penis is erect but it is not as big as other times and i can only nut like once or twice. is this normal? how come my penis is different sizes when i have sex? |

I reckon this depends on the level of our excitement and how much blood enters the penis. It happens to me too.
Tell me, do you work or study? I can’t believe you can do it for 8 times a night!?! How do you do this? And where on Earth do you find the interest for?
OK, I’m 30 and employed. That makes all the difference. Believe it or not, sometimes I am so tired, that I don’t even feel like it.
Anyway, whatever happens, it happens in the brain first. Both physical and mental stimulation begins in the brain, which makes the nerves in the brain send messages to the penis nerves to relax, so that the blood flow can reach penis freely. Blood fills the corpora cavernosa of the penis, high pressure traps the blood and an erection occurs.
So, everything’s up to the blood supply and the nerve connections to the penis. Simultaneous contraction of the muscles at the base of the penis prevents the blood from draining out through the veins. This way, an erection is maintained. |
