This is extremely common. My shaft is covered with hair all the way out to the circumcision scar. My curiosity is what I would have looked like if I had not been circumcised. I wonder if a foreskin has the ability to grow hair?
In heterosexual sex the only problem is during oral sex where the hair can pinch or find it's way into the mouth of the person performing it. In gay oral sex some men find it a plus viewing at as a masculine ornament and others find it a big negative looking at some different aspects.
If you are one who is on the receiving end of oral sex frequently it is possibly better to shave it.
If there is a considerable amount in heterosexual relations the hair creates friction on the vaginal barrel and will add sensation for a female and can be a distinct positive.
Personally, I do shave this one area because it is a pain in the neck and my other half complans somewhat about a mouth full of hair. In men of mediteranean ancestry or other people who are extremely hairy this is common and if you find a person absolutely covered in hair, odds are about 60% better than average that the shaft of the penis will be a reflection of the rest of the body hair quotient as well.
You are not in any manner abnormal and as you age the hair will be guaranteed to multiply. If you are at a time in your life where your best friend and sex partner that receives the valentines day card is one of your own hands the hair is an asset because you can use it as an erotic thing in jacking off, with a partner it can be a less than positive thing.
Good Luck. . .
