If you can't get your penis fully erect through normal means then see your doctor and be may give you a prescription to aid in achieving fuller erections.
Stroke it gently and remove your lowermost front ribs so you can lick it and suck it. If that doesnt help, get a girl to do it for you. If that doesnt work, good luck getting laid you fool.
By simply rubbing your penis, in other words, masturbate.
If you can not hold an erection, then you most likely have erectile disfunction. You should talk about it to your doctor.
Touching it
The size of a guy's penis when flaccid is not a good indicator of the erect size. Even a penis that looks small when flaccid, can grow to be of very respectable size when erect. Conversely, men who have a penis that looks large when flaccid, generally don't see very much change in actual size when erect.
That is perfectly normal, and nothing to worry about.
Penguins have an erect posture that includes a large head and a short neck. Penguins also have very stiff wings.
A human penis does not grow that long as a rule. There may be an exception to this but it is very rare. I think the longest recorded was 15'' The average penis is 3-4'' flaccid and 5.5-6'' erect. An animal erect penis can reach feet in length ! ie ; whale and elephant for example.
Yes. Men are very unique in the variance between flaccid penis size and erect size. Some men are called show-ers and others are called growers, in other words, some men have large flaccid penises which don't get much bigger when erect and others have very small penises that erect to much larger sizes.
When you are sexually attracted to someone you are about to have sex with your penis will automatically erect ready for it. If it does not then you may have an erectile dysfunction or be very nervous. The first time a male has sexual intercourse he may find he is nervous and not erect or he may find he ejaculates very quickly (Premature ejaculation). The thing is not to sleep with lots of different partners. Have a loving relationship with one partner and you should not have erection problems.
Only the male Sloth has a penis, it is very large ranging from 8-10 inches in length when fully erect (sexing an adult male from female is difficult due to the males large penis size.)
It depends on what state of puberty the 13 year old is in. Some 13 year olds are more developed than others. If one is slightly behind on development, a 3 inch penis would probably not be small and it will get much larger in a few years.
The size of a man's penis is very variable. Each man is different. Some have smaller ones, and others have larger ones. Also the size of the penis when flaccid, is in no way related to the size of the penis when it is erect.
If it is stiff and longer than 5-1/2 inches from the bone behind the top of your penis to the tip of your penis, then it is above average. Size means very little . . . don't get hung up on size.
Well most of the time, when you have an erect penis, masturbating is very easy the amount of stored energy changes... right answer
I would say that a 2.7 inch long erect penis was probably towards the larger end of average lengths for an 11 year old. Flaccid penis measurements are very unreliable as changes in temperature and emotional state can effect the length of a flaccid penis. You must have noticed that your flaccid penis is longer when you get out of a hot bath or shower than it is on a cold winters day.
