Why do men most always wake up with an erection?

Answer 1

you have to ask that at your age?
Its because men have sex on the brain and its to bother us women

Answer 2

Often referred to as ' morning wood' , the more formal term is nocturnal tumescence and seems to correspond with REM periods of sleep. The question of why is often claimed to be urine retention. Most guys know the frustration of waking up with a stiffy and having to pee like crazy, and although not impossible to urinate with a hard on, there's nothing more amusing than watching a guy trying to lean as far forward as possible to get that thing aimed somewhere near the bowl. Given a few experiences like that and it's easy to see why most guys would come to this erroneous conclusion. However, a more likely cause, or need, for nighttime stiffys seems to be oxygen. According to a well decorated sex research psychologist, Al Cooper, ' The penis lives in a low oxygen state. Nature takes care of this by making sure the penis gets enough oxygenated blood through erections.' This is not a 'written in stone' theory since the argument could be made that there are more erections at night because oxygen assists with the erectile chemical processes and oxygen levels are higher during sleep

Okay I will try and explain how erections happen but you will be most amazed by the fact that most of the time (at least in young men ) we don't do anything. Also, you will have to put up with a long explanation. In order to have sex a male penis must be erect. That erection is related to physical health, mental health, and emotional health (ego) If a male is threatened or scared or has anxiety about sex he may not be able to get erect. Erections occur when more blood is pumped into the special tissue in the penis than can leave. The arteries carry blood to the penis and the veins carry blood away from the penis. When the brain gives the command the arteries dilate (become very large) and more blood is pumped into the penis than can be carried away by the smaller veins. The result is the penis becomes engourged with blood and becomes erect. When erect it becomes more sensitive and sexual arousal is easier. The following things will trigger the command in the brain so that an erection occurs. Physical stimulation (the boy or other person touch and rubs the penis), visual stimulation (the boy sees a girl, a picture, or woman in a form of undress that triggers an erection) Males are genetically engineered to be set off by visual stimulations. This is one reason why most users of pornography are males. In childhood and early puberty (5 to 13) boys can get spontaneous erections. The brain just decides to trigger an erection. This is very embarrassing to boys because it happens at school, while at play, in front their girl friends, in the shower during PE. The boy does nothing to cause this it just happens really! Girls think boys are always horny and that is true for teen agers but boys don't do it the hormones do it to them. Mental stimulation, sometimes just thinking about a special girl or having masturbated last night etc. will stimulate an erection. Boys get no rest while they sleep either. While a boy sleeps at night he usually has up to 7 erections in his sleep. And if he has not masturbated for several days and is of the age to produce semen he may have an orgasm in his sleep ( a wet dream ) in which he shoots semen all over his PJ's or briefs and the bed sheets. It is usually a rather large amount. Then in the morning he wakes up with a very hard erection that is the result of pressure from a full urinary bladder on the veins in his penis. That has to be dealt with in some way so he can urinate. Erections are very much a part of a man's life. In our youth we do not do a lot to cause them they just happen. As we mature and enter puberty we learn to take charge of our sexuality and to control them to some degree but not totally. A man can cause an erection by physical stimulation, visual stimulation, sex play with a partner, or mental stimulation or fantasy. And most men use those things to get erections at private moments in order to masturbate in private and release all that sexual tension. When a man gets a partner then she helps release all the sexual tension and love making or having sex envolves physical, visual, and emotional stimulus.
I hope this helps you understand your boy friend a little more. And realize that sometimes you may trigger an erection when you don't really mean too. When that happens do not think to ill of your boy friend.

Not all men have erections every time they wake up. If you didn't know, the average male has an erection for a total of 100 minutes a night. It's just how your body makes sure your plumbing is working properly.

Answer 5

A morning erection is naturally caused as the brain enters tREM-deep sleep phase. At this stage, the body's skeletal muscle structure relaxes and causes hypervasodilation in the capillaries of the body, resulting in an erection.

A NARB (no apparent reason *****) after waking up is usually caused by a full bladder pressing against the prostate.
