"On a good day I'm 1/2 inch bigger"?

I vary in length and girth when erect - I have no idea why, but have been like this since I can remember. I have a theory but you would laugh at me.

When erection is fast size is low , when erection is forced with a lot of blod artificial pumping by hands lenght is bigger , but may premature ejaculation in such case affect .
It is a litle similar to pomp sistem .
AS even as example a rigid metal can't be blend as a soft , but soft could expand and blend easy with friction and heat even can increase lenght or expand ,

I think this is it, here. For me anyways. My measurements at a full-strength erection ("a good day") are about 1/4" bigger than other measurments I've made.

its bullshit... since it is always the same... you want to believe you are .5" bigger because you are feeling better and bad measurements are taken.. if you want to know if its true puch the ruler until it hurts ( be erected though) there are some erections that even if u stop wanking it, it stays up for a few minutes then there are other days that it stays up and in 5 seconds it starts to fall. :) either you have good days always or you got 1 good day out of 15 :) that would suck.

Sometimes we get into a serious bondage session. If I am restrainted for several hours and kept aroused, it does appear that there is more blood pumping in my cock and it looks thicker. I can't say it appears longer, but thicker yes.

On a good day I'm bigger. But for me it depends on how long I've been hard. Like if I have a semi and a couple hard ons through the day, it'll be fatter towards the end of that day.

I can be fully hard, use a small thick rubber band to clamp with, stroke my cock, release the band and trap blood in my cock, wait a bit, stroke, and trap more blood. I can easily gain a little length and girth, and have used this exercise to expand my cock head and girth the length of my shaft. this is a very short term exercise and gain, and i use this after some jelqing sometimes.

I feel sorry for all those people living all their life on bad days :b

Hehe... did you see what happened with that last pic that Hitokiri posted on his gallery? I commented saying that the halo effect around his cock made it seem like the picture had been photoshopped, especially where the piece of wall near the tip of his cock actually overlapped the door frame(!), and a couple of hours later he deleted that picture (along with my comment) and reposted it after fixing the halo that I had pointed out.

So I just helped Hitokiri improve one of his fake pictures! I feel slightly complicit...

Anyhow, to the OP, I don't get it either... I can't really think of a valid biological mechanism by which someone could gain a inch in length just by being really turned on. The length, as far as I know, is limited by the suspensory ligament. I can see how someone might be a little thicker, but certainly not a whole inch longer. My length is very stable, and has been the same every time I've measured it since it stopped growing.

It's a law of physics. The larger a guy is, the more he can vary during erections.

I'll laugh at you anyway - so you may as well tell!

Actually, I think there is something in it. I recall one time, on the second day of a holiday with my man, removing his clothes and finding myself thinking his cock looked bigger. I remarked "Hey, have you shaved or something? You look bigger..." because I assumed it was an optical illusion, he can't have grown overnight - his response was "No, that's the same as yesterday, I'm just well rested" - I'm not in the habit of measuring ('cept by sitting on the damn thing and bouncing, like the good Lord intended!) so I have no idea of a volume increase - but there was a difference visible to my eye.

My somewhat off-the-cuff theory is that guys with bigger cocks require more blood for a harder, full-on erection and any effect of things like tiredness and such can make a more perceptable difference - not to performance (well not in the case I'm talking about) but to the final percentile of erectness.

I have 1/2" variation between a weak erection and a strong one. I think that the variations are caused by hormone levels, fatigue and diet.

This is really the age old argument between 'grower VS shower', is it not?

I mean a 3 inch flaccid / 8 inch erect cock grows nearly 5 inches, no? Not just 0.5" or 1".

If you are familiar with a large cock you understand what being BIG is and what being BIG and ROCK HARD is.

I'm a grower. When I'm exercising I'm about 3-5", when my cock is 'getting hard' but not rock hard it can be up to 7" (before even pointing upward, and I point STRAIGHT up), and lastly when erect and rock hard I'm always 8-8.5" ...

BUT that isn't to say with one strong flex of my cock or more arousal getting to 9" isn't possible ... the same way going from 3-8" was possible in the first place, getting that little extra is also possible.

Now I'm not saying once I reach 9" I can just FLEX again and hit 10" ... that is not going to happen. But as a grower I can definitely put on 0.5-1" anytime I want too... it is only 2.54 cm ya know.

I think that maybe the OP's point is that if you are going to post an erect measurement, why would you post anything other than your length at full erection? There doesn't seem to be much point in saying "I'm 8 inches but on a good day I get up to 8 3/4." You either have an 8 3/4" erect cock or you don't.
