So, what is it that makes some cock heads really big and some smaller? (I have noticed this in real life and when browsing cock pics in profiles here) Is it the way you were circumsized? Is the sensation different? (not that you'd know since you only have one head, but any insight would be interesting to know). Thanks!

I would have to say its just because all of us males are different in our own ways. Why are not all cocks the same???
Maybe having a certified medical doctor answer this question would be better for us all.

Heredity.

its just down to nature, sometimes my head gets bigger than other times .. an i dont mean in a vain way

Mine seems rather proportionate to the rest of "Mr Happy" I'd hate to be swinging a sledgehammer or anything
as far as feel? It feels good to me ;P

I have a large mushroom type head, it gets larger as I get closer to cumming. I think this happens for every guy.

I have a 6 inch uncut one with a proportionate head. It does not change size once the penis is erect, even during ejaculation. Parts of the foreskin are much more sensitive than the head, and the pix of cut dix makes me think some of this is lost to the butcher's knife. I also have noticed that some variation in masturbation techniques between cut and uncut guys. When I was a small kid, I noticed my dick was 'different', but as an adult I feel that circumcision should be regarded as a kind of sex mutilation and relegated to believers and practicioners of tribal and other cultural/religious ceremonies.

My little guy's head most definitely swells. The hotter I get, the larger it gets. I think it is just the luck of the draw. We are each dealt a different hand. It is how you play the game that makes you a winner.

Maybe the same reason some women have large flat nipples and others have small pointy nipples.
(doesn't matter, they are all suckable)

I think it's mostly genetics. My head swells so much sometimes that it's thicker than my shaft. I think I'm gonna start calling myself "the hammerhead"! lol!

I agree with hard40, the closer I get to cuming the head begins to swell and is more deined, and the better it feels as I stroke it. Probably it gets bigger as a guy cums so that it acts like a plug in the hole it is places to keep the jiz in place. LOL

It was how you were circumcised, imo. A thousand doctors do it a thousand ways, so there will certainly be variation. Though it looks like the head swelling is pretty consistent, mine does as well :p

I suppose that cockhead size and type (e.g. Mushroom or Plum shaped) is due to genetics...like penis size.

Mine swells in proportion to the shaft as I'm aroused. It seems like it may be larger when I'm super horny, but maybe it just FEELS that way.

One time, I took a close up video of my penis during ejaculation. My first muscle contration didn't shoot any cum, but caused my penis to jerk and my cockhead to expand slightly, but very noticeably, like it was being pressurized internally. Then, the second contraction shot the first cum and my penis jerked with each succeeding squirt. The cockhead stayed at maximum size until I started losing my erection.

BTW, Looking at an ejaculation in freeze frame and super slow motion is very interesting. Seeing a big jet of cum shooting out of the end of your penis and frozen in time is AWESOME!!!!

Differences due to circumcision certainly occur. I wonder if widespread use of the circumcision ring they use on little boys now makes the process more consistent. (Seems like a plastic ring clamped on your penis and squeezing your foreskin till it falls off wouldn't be very comfortable.)

so what size of head do you like secret?
