How is this possible? My semi-erect penis is bigger than when fully erect

Yep it is strange, so now when I am doing my girlfriend I sometimes do it on a 85-95% erection level. Works well this way..

I don’t know if I’m larger in length or girth when partially erect. I have noticed, however, that when my penis is not turtled, that it is actually thicker flaccid than it is when erect (probably .25” thicker). I just need to get my penis to be like this when it’s flaccid all of the time. If anyone finds a way to get rid of turtle dick once and for all, hit me up with a PM. ;)

PS
That my non-turtled flaccid is thicker than my erection is made even more noticable after I do a specific kind of warm-up, which is placing my penis in a glass of very warm water.

It’s the skin. Tunica is rigid so its width is less or equal in semi-erect state than in erect state. In fully erect state skin stretches more than in semi-erect state. Also the thickness of the skin varies a lot and depends on body condition, veins’ dimensions can change and also there is such a thing as lymph buildup.

The tunica is not rigid, or it could not expand when your penis goes from flaccid to erect.. The Tunica is comprised of smooth muscle, collagen, and elastin, all substances that are flexible, and stretch.

If the cavernosa expand more laterally at 70-80% erect and more longitudinally at fully erect, the larger girth could be explained. Perhaps it is a mechanism of penile physiology.

I also have to agree with RTG’s explanation, mine also looks fatter when it’s not fully erect. It must be stretching the tunica forwards and in the process narrowing it.

I love how I had never heard about PE until about 2 weeks ago, only to find that the people on here are actually seriously knowledgable on the penis anatomy and this science, it’s great and intreresting, especially questions like this!

My dick is 6 7/8” long while semi-erect and only just over 6 1/2” long hard.

I measured just after a clamping session a month ago and got a real shock when I discovered an extra 3/8”.

i think what happens is that as I become harder the tube expands somewhat robbing length for girth.

I have since stopped girth specific exercises like clamping, even though it is my favorite thing to do, because I want length and the general concensus is that we should do length exercises first then go for girth….and I`m happy with 5 1/2” of girth and so is my wife.

I would rather 7x5 than 6 1/2x6.

sorry girls.

Same here. My girth when semi-erect is visibly thicker than when fully erect. However, I am longer when fully erect than when semi-erect. I thought it was just me but glad I’m not alone! :)

Try pulling back your balls when you get an erection. It could be Turky neck. My dick adds on about 2cm when I pull my sac back.

You’re saying his larger girth at 75% erect is due to turkey neck? Someone did comment also it could be the skin. I think that’s more probable than tunica changes.

I’m another one who has this. Girth is slightly higher when semi-erect than full strength erection. Seems to be fairly common.

Same here.

Was just looking for an explanation on this as I am 5 1/4 erect and 5 3/8 to 5 1/2 semi erect, as this does not apply to my length in any way.. Thanks fellas!

Potential girth gains on the way maybe?
