Males are the only ones that get them.  They occur when a male gets excited and blood flows to the penis. They are also called erections.

I have never seen a red string under the skin.  Like Dainelle said it is probably an artery.  It is probably the artery that leads to the brain or the one that supplies blood flow to the head.  I suggest looking up chicken anatomy.  I serious doubt a string was embedded  in the skin of a chicken.  That is not possible.

Your brain is sending a signal of arousal to your penis.  Blood is then rushed to that area, making it hard.  It just means that you are healthy.  In the long run, you may be less susceptible to prostate cancer, impotence (erectile dysfunction).

The head of the penis - the gland - is actually made  up of thousands of nerve endings. After an injury, and the gland repairs itself, the nerves may not be rebuilt exactly right. There sometimes is scar tissue. This is just the normal course of things. He may always feel some "phantom" sensations. It might lessen with age, but his best course of action is to rub daily with vitamin E oil - it helps the skin repair itself, and when having sex, if it gets to be too much, have a de-sensitizing lotion handy to apply when he feels he needs it. They are available at drug store made especially for the penis.  I hope that that helps.

Circulation of Blood..

sounds like peyroines disease. 90% of males have it it basically means curved or bent penis. it's nothing to be alarmed or worries about unless it affects your sexual life. and if your foreskin isnt sufficient??? whats the problem?. Im not sure if I understand your question. foreskin is supposed to retract when your erect. Thats normal, unless you want it to cover the entire head when erect, then you would need to restore your foreskin further so that you will have over hang. Hoped this helps.

i just seen a show about buried penis, and usually when a penis is buried it is caused from some extra skin around the sac, either on one side or can be on both sides.  and this can also be caused from not such a good circumcision at birth, but 85% his penis will not grow the right way and it will stay buried, the only thing you can do for this is take him to see the doctor, but right now is too early.  he may even want to do this when he gets older too.  the doctor will remove the skin that is making his penis buried and then he will add this skin up behind the penis and this will keep the penis in the correct lining.  but no need to worry if you all dont have this done, he can still get a full erection and the erection will come completely out how it is suppose too.

Veins carry deoxygenated blood from the organs and tissues back to the heart.\nDeoxygenated blood from the body enters the right atrium through two great veins, the superior vena cava which drains the upper part of the body and the inferior vena cava that drains the lower part which drains the portal cyrculation too full with nutrients to nourish the body.

not sure but maybe it has something to do with the blood vessels around that area

Yes, you can lie down if you request it.\n\nThey will tie a rubber band around your arm at the bicep.  This causes the veins to swell a bit, making it easier to find them.\n\nThey will insert a double ended needle into the vein and then put a vacuum tube on the other end.  It will fill with the correct level of blood.\n\nDepending on what tests the Doctor ordered, they may fill several of these tubes.  The use of the double ended needle means they only have to poke you once.  They may ask you to make a fist.\n\nAbout the time they are done they will remove the rubber band.\n\nYou get a cotton swab and then a small band aid and you are finished!

Circumcision is the removal surgically of the foreskin that covers the head of the male penis.

Depends how seriously the vein gets punctured.  Essentially it's puncturing the vein all the way through both sides.  If it doesn't heal quickly (or well) you get a bad bruise from all the blood that seeps out of the punctures, and it can cause nasty internal infections as well.  If the vein is already weak, it can collapse, severely damaging blood circulation and purification in the body.
