Misfires, Why?

[Stew52]

We've read a lot of post here about guys "misfires", wherein the injection did not have the intended effect. They still happen to me occasionally after 4 1/2 years. Shooting while plumped helps immensely. Sometimes there are easily explained by not getting the needled into the cavernosa but into the outer tissue. For me this produces a painful red welt. It usually happens when I do the shot while more flaccid or I hit a tough spot on the tunica. Once early on I hit the urethra.

BUT. But this does not always explain a diminished effect we have from time-to-time. On occasion I've had to go back for a booster.

The cavernosal arteries run approximately down the middle of the two cavernosa, supplying blood that apparently flows radially (?) out to veins on the outside. The two cavernosa are separated by a septum; I have no idea how permeable it is.

Three things. 1. How permeable is the septum and how well does blood flow well between the two cavernosal siades? 2. It would seem that any shot into the cavernosal spongosa tissue would be more localized hence the need to massage it in. I've also been pinching the base to reduce blood outflow while massaging. 3. If purely by chance you got the injection INTO the supply artery, it seems it would be better distributed, especially if nearer the base of the penis and flowed down the length. Shooting it more plumped would reduce the odds of getting it into the artery as there is more engorged spongosa tissue. This factor alone may explain better results from time to time.

Appreciate your thoughts.

Thanks for all that useful information and diagram. I had a little blood last night when the needle went in and injecting was not as smooth and painless as usual. I still got a good liftoff but maybe 90% of usual. After I noticed a minor red spot.

Can you give a probable diagnosis to that type of "near miss"?

Also re penetrating the septum -- I had read of one guy's method of injecting half on each side so as not to rely on flow from one side to the other. Not that I'm looking for more opportunities to inject but do you think maybe that's the way to go for effectiveness as well as preventing peyronie's ?

Thanks for any opinion.

It sounds like you might have drilled a small vein and partially injected too shallow.

The vast majority of guys don't need to inject both sides. You shouldn't need to. To help prevent peyronies and scaring you should rotate sides not increase the number of pokes.

I have a hard time explaining small to moderate deviations to efficacy myself and 90% is within that band of mystery. Sometimes I have to do a boooster. (And sometimes I plan a booster for a longer session.) The small amount of blood and a 1/8" bruise is knicking a surface vein. About half the time I get a drop of blood when withdrawing the needle. About 1 in 10 a small 1/8" bruise.

Damn, s#it, c&ap - I went and did it. A nice moderate misfire. And I know why. I have a really tough spot on the tunica mid-rear-left. Like it bends 30ga needles if I hit wrong. Frequently needles just depress that tough spot on the tunica in and I think I'm ok. But I'm NOT in. I try to hit that spot occasionally just to mix it up as the book says to do. So I guess the 0.20 of 80mcg/ml PGE did not penetrate and stayed outside the tunica in the skin layer. The R 0.20 made it in just fine. Big red swollen welt halfway around near the base after sex. I knew it was stinging but soldiered on to make a happy content customer (wifey). Iced it for two hours after and it's getting back to near normal several hours later. Sometimes I have drilled the needle into this spot but figure that's not good, but no more hitting there now.

PS: AFA dual injection a/c the septum, I have never heard a professional opinion on how permeable/interconnected the two sides of he cavernosa via the septum are so I'm not sure. I will ask my Uro at the next opportunity. I was hoping for a technical answer here. I'd think that changing up sides alternately as recommended though would address the peronies damage issue insofar as possible. In 4 1/2 years I've had no new bend, just a typical upward bend. Some straight, some up, some down.

Stew52: When I hit a tough spot I spin the needle and it drills in better.

As I said above, I've tried that, "Sometimes I have "drilled" the needle into this spot but figure that's not good." But the thought of taking a small cookie cutter piece out of the tunica, however tough, seems worse than a plain puncture. So I don't any more. I'll just avoid that area.

I use an auto-injector and I cannot figure out why sometimes my 3-4 units gives me 1.5 hours and other times, like last night, the exact same dose gives me 4 hours and an injection of antidote. It doesn't seem to matter what side, it's happened on each at various times.

[Stew52]

A. I just don't think we know enough about the detailed anatomy as I've queried above, and, B. We were not built symmetrical and perfect (and injuries and scar tissue). And many's technique varies from R to L (handed). On average I get a good 1 hour but it can vary from 30 minutes to 2 hours.

I’m not a Dr and anything I say is nothing but my opinion. I’ve been injecting for about 9 months and usually 2-3 times a week. I’ve only had three misfires in all these shots. I use a 31g 5/16in needle. One misfire is the only time I used a 1/2 in needle and I shoved in in all the way as usual and obviously went into the urethra, as soon after while trying to massage up a hardon which wasn’t coming… the truck mix solution dropped out the top of my penis. On one other occasion my wife was getting very frisky and was performing some amazing oral on me which very unusually gave me a good erection as I had taken some cialis earlier. As past experiences go I would loose my erection before I could get started having intercourse… so I said hang on a minute and ram to the restroom to get a shot. It was the easiest shot ever! Only problem is my erection was going away very quickly as I was administering the shot… I assume all the solution I injected washed out along with the blood as my erection faded quickly… talk about a ruined night!!! Was afraid to use another shot so just called it a blue ball disaster!! I have however noticed the same as mentioned in the original question. I feel sometimes when my wife and I have very active vigorous sex your heart races and you tend to wear the truck mix out of your penis as in my case I have a VL which obviously looses some blood but is quickly replaced as long as the excitement is there. On the other hand using the same amount the wife and I have just has a quicky or she masterbates me I can usually maintain an erection for twice as long as there’s not nearly as much blood moving in your system. Fir the same reason people on FT will tell you if you need an erection to go away you should walk exercise do set ups or anything that gets your blood flowing. Just my two cents .
