The physical and psychological triggers underlying penile erection are fairly obvious. What happens at the physiological level, however, has proved harder to discern. To that end, study results published today in the Proceedings of the National Academy of Sciences will no doubt prove insightful. According to the report, the same chemical compound that causes an erection also maintains it over time. The findings could aid efforts to develop treatments for erectile dysfunction.

Building on previous work indicating that the release of the neurotransmitter nitric oxide from nerve endings in the penis produces erection, a team of Johns Hopkins University researchers led by Arthur Burnett focused on the role of the compound over time. Their research on rats and mice indicates that nitric oxide released at the onset of erection dilates the blood vessels, which enables blood to flow to the penis. That increased blood flow, the team discovered, slightly stresses the blood vessel wall, which prompts the release of more nitric oxide from the cells lining that wall, relaxing more tissue and allowing more blood to enter. The process repeats, sustaining erection.

The investigators conclude that drugs that prevent the inhibition of nitric oxide production might alleviate impotence. "The physiology of erection is like driving a car," Burnett remarks. "You can't just turn the key and expect to go anywhere. You also need to hit and hold the accelerator." --Kate Wong

kmguru,

Interesting... ;)

I will never need the drugs though... :rolleyes:

It can point to the east if you like.

I just know that one day south is where it's gonna head. :D

Usually transient don't worry

Live long (an' hard) and prosper:D

Doubt it. I don't see how using the extra muscles it takes (and only the more exotic positions require that) could increase the amount of a neurotransmitter.

Besides, the Kama has a undeserved reputation, in my opinion. A great deal is devoted more to the social dynamics of sex than to sex itself.

Of course, the chapters on the correct conduct of a courtesan are delightfully cynical.

Edit to add: You kids quit flirting!

North, north, north... :D:D

Too far east means peyronies disease!! :D

Get a room!

*Grumbles*

This is a serious thread and you two are acting like schoolgirls.

Ya know you can take erections a little too seriously dear. :o
I thought the boards were all about interaction.
Sometimes I think it's okay for that interaction to be a little light hearted, wouldn't you agree?

Loosen up honey you're a long time dead!:D

That was a decidedly un-serious reply on my part. You simply need to interpret tone without the emoticons.

Besides, if we have another couple proclaiming thier love all over the board I'm going to puke. :p

Sorry Xev Didn't mean to piss you off
accept this rose with my love

@}---->--

Not pissed. I am in a good mood. :D

(Don't know why....I shouldn't be. :bugeye: )

XEV
Course you should be you're a person with a good mind and none of the baggage that makes MY life a chore. You wanna spill, I'm a good reader?

I don't Love her...

We just play with words... :D:D:D

Loose up Xev!! :D

T.S.
And you call yourself christian.. Now say you're sorry!
Remember baby jesus is watching U:D

I'm just human!!
I'm just a Child of God!

Can I play, please!? :bugeye:

Sex is a common part of our Nature...

A goooooood part... :D:D:D:D

Love,

OH ALRIGHT!

Wait lemme just get a condom:D

One of the things that ever most intrigued me is cyber sex... How can this be done? I can't imagine such thing...??

It's like any form of pornography or external stimulation.

90% of sex happens in your head. The rest is physical stimulation of your genitals. Cyber sex is just another person typing away (Presumably with one hand) telling you stuff they think you wanna hear depending on your last post.
The images produced by the written word or the webcam are then transposed by the brain into horny stuff.

Works for some, not for many, but hey what the heck, whatever floats your boat, thats what I say!:D

90% in the head!?!?

I don't think so... :rolleyes:

:D:D:D:D

It's not what it seems, at least...

Do you have webcam...?

... just kidding... :D:D:D:D:D

Not my theory, actual fact. think about all of those nerve endings being stimulated. has to go somewhere, the brain right? My line is sexual health, I know of what I speak. think about when you service yourself a lot of the time you have your eyes closed right? I rest my case


Oh and...
yes I do but what would jesus think?:D

Yeah... but I suppose you FEEL it there... isn't it...?:D

The brain just processes the information and the senses... but that doesn't mean thoghts.

You can say that 90% has to do with your head... but you can't say that it's thougts...

90% is what you feel. ;)
(Thank God...!) :D

About the web camera...
I don't know how it works... :(

Well... but if you know... tell me!! :D:D:D

Love,
Nelson

Naughty Boy!! three bloody mary's

Sorry about my hormones...
They are wild today...

Ah, this is a thing us boyz never get control over.
Never mind ay?:D

Unfortunately not. The amino acid Arginine does improve "NO" synthesis. Tantra Yoga can help too. Males are always visual and in our society as you get older, you get desensitized. The visual signals does not produce enough signal level to act on those areas. I remember my first yoga class when I was 23 with 12 beautiful young ladies. I had problem the very first two classes - after that I got used to the visual and pheromon senses and has been teaching for 30 years with professional ethics. It is all in the mind.

Sex is 90% mental. Think about how some guys (and women, though I think it's more common in men in today's society) only are able to get off on certain ideas (such as youth). Also, though I guess you don't really know this yet but, certain things will make an experience, ahem, shorter. Those things are definetly mental. Look at role play. The reason for that is because it can be more arrousing.


bbcboy....I'm pretty sure Jesus has already locked heaven away from me so.....Pavel_9@hotmail.com

!

Why Tyler are you hitting on me?:o

How cool:D:D

Not sure you could handle my level of debauchery tho'
Maybe I'll have to go easy on ya!

kmguru,

Well... I don't need it anyways... :D:D

But if someone needs, try meditation. I have a hard time trying to wake up my kundalini because my energy instead of going to my Root Chackra, it's deviated to... er... another place... :rolleyes:
:D:D:D


Er... Tyler...

I know you are hetero (as me...:D) and like women (as me...:D)... so I would like to warn you that bbcboy is not a girl...

Love,
Nelson

Like duh!!

Sorry T.S. I just thought the name might just give it away

What say Tyler?

Erection...

Far as I know, you play with it,
it gets hard.

We have a family friend who played with her husband's "it" and it did not get hard for many years. It caused too many problems - finally they got a divorce....(there were severe mental/emotional problems associated with it)

I'm sure I'll get there one day.... 'scuse me, there's a nail needs knocking in :)
