How long does your penis stay completely erect

7x5.5: Ok, ready for a somewhat hypothetical question?

Your girlfriend is out so you are watching a porno, and bring yourself to a complete hard on. You then turn off the porno, and cease any sort of contact with your dick (ie take your hand off). You also cease all sexual thoughts. How long until you lose your erection / your erection loses its angle?

My penis seems to require continual stimulation to keep enough blood in it to keep it fully, rock-hard erect. If I have a full erection and all physical and mental stimulation ceases I start to lose some of my firmness almost immediately. I do not lose my erection completely though. In such a situation I would go from full hard down to about 3/4 hard very quickly and hang there for awhile before deflating further, but at that point a couple strokes and squeezes will bring the full erection back.

I have always wondered if this was just me or if it is size-related. As a straight guy, I have seen relatively few other guys' erections. Of the ones I have seen, mostly in gym showers/locker rooms, many guys (with erections much smaller than mine, as most I have seen are) seem to be able to just stand there with a full stiffy for a long time without touching it. (Of course, I probably flatter myself in thinking there is some connection between my presence and those persistent stiffies. :) )

I "can" keep it hard pretty much as long as I please with just a few strokes.

Without ANY stimulation, I would say maybe 5-10 minutes. If I want to turn it off....think dead kittens or something.

7x5.5: Donk, you are the same as me. About 10 - 15 seconds after no stimulation, my penis stays about the same size or slightly smaller but loses its angle. She needs a few strokes every few seconds to stay rock hard and pointing out. Although it doesn't really affect anything, I wish it would stay hard without stimulation for longer.

I've never clocked myself, but I stay hard a while. Takes me a bit to get hard, and a lot longer to get soft, even after I shoot. I remember once getting a phone call in the middle of sex I had to respond to. The call was a minute or two and I had to make some notes, so my hands were occupied. When I came back to bed, my girlfriend commented I never went soft, and was I ready to remount?

Take care

There used to be a TV commercial for Toosie Pops. In it someone asked the wise old owl how many licks it took to get to the center of a Tootsie Pop. The owl unwrapped the sucker and started licking. "One, Two, Three." The owl couldn't resist and bites down on it and answers, "Three".

Same for me.

I've never had the self control to check. If I'm jacking off and stop (yeah, like happens) I think it disappears pretty quickly. But, if I stop and think about it or take a look down, I can't help jacking it some more. If I'm paying attention and watching it, I'm playing with it. If I'm not paying attention to it, who knows.

More power to you if you clock it.

My dick points straight up when hard. If stimulation stops, it starts to lose the angle almost immediately, but it stays big and full for at least five minutes. The rock-hard, straight up angle will return almost instantly when, thankfully, stimulation resumes.

I am more similar to Donk than Mrsparkle. Without stimulation (mental or physical) I tend to deflate to about 3/4 erectness. The thing is that I can stay in that state for quite awhile. At my size a semi can be anything from 8" to a rock hard 10.5".

I believe that for especially long penises and even more especially for those for which flaccid and erect size is dramatically different (as in my case), there is large amount of blood that must be coaxed into staying where it normally is not located. Therefore it takes some intervention during lulls to keep all that fluid entrapped there. It just goes with territory (poor us having to continue stimulation to keep the giant standing tall) I think. Guys like John the Horse on other hand have a smaller differential in blood needed to go from his flaccid to erect so perhaps that is why he and others with closer flaccid and erect volumes take less effort to regain and keep total stiffness.

This somewhat age related I think. I once stayed totally hard for 10 hours. But then I was 22 and I had "help" and I don't mean Viagra. I doubt even with someone "helping" I could do that today. I probably would need Viagra.

well i have what me and my roomate call "erection cancer". This is were i get erections all the time for no reason and they last FOREVER. I can useally without touching it or watching anything etc. stay hard for hours and hours and hours. They only way i can get rid of it is to jerk off, and even then it doesnt allows go away. I guess i should go into porn lol

As one of the older men on here I can confirm that age has an effect.

Back in my 20s and 30s it was not at all uncommon for me to retain an erection for an hour or so, in those circumstances, driving for instance, where no action could be taken to deal with it, and it would just pulse and throb and jump about, as if it were trying to escape from my jockstrap. These days that happens less often. On the other hand, I still get enough unplanned erections to make it a regular problem for me. Any sort of travel seems to bring them on for some reason.

In my case they divide into two categories. Some are the gentler ones that might go away and come back a few times if I turn my thoughts elsewhere, and they allow me to get on with whatever I am supposed to be doing. But the wrong sight or thought, or maybe something I have eaten, can sometimes bring on the sort of raging hardon that will not relent until action has been taken, whatever happens, and however hard I try I can think about nothing else until I have satisfied it.

I think one factor in my case may be that over the years there has been a gradual but steady increase in my resting flaccid size; I used to be more of a grower, less so now, so the inflow of blood required is probably less. Unlike Donk I don't find that a really class A erection needs stimulation to maintain it; but in any case when I get one I find it almost impossible not to take some sort of action or another.

It can take me as long as half an hour to lose my boner entirely if I don't think of sex at all. Starts to deflate after about two minutes, though. But I'm 21.

I would need 911 also.

Any numbers to support your contention of enlarging flaccid size. If you could bottle that somehow, it would be invaluable in helping those with large penises more easily get a super erection as life progresses. You lucky dog.
