I had to purchase longer needles and just wanted to make sure if I were to inject too deep, other than the medication not working and pissing it out, is it dangerous?

When I was learning, I had blood coming out the meatus once or twice, from hitting the urethra, when I used the 1/2 in. (13mm) needles, but that caused no problem, other than no erection. It stopped in a minute or two. I think I went right through the corpus cavernosum, which I later measured at 0.2 in. (5mm). I soon switched to 5/16 in. (8mm) needles. My penis is thin; I think the 1/2 in. needles are for thick penises.

I've hit other structures in the penis and gotten hematomas, big ugly red swollen bruises which took a few days to disappear, but which were harmless.

I suppose you could do damage by hitting a big artery or vein, but I've never heard of that happening from any FT guys.

If you inject too deep it will have way less effect. As long as you don't hit a vein all should be fine. Best would be to go see a doc to be instructed on proper method.

On one occasion I was a little to aggressive with my injection and pierced my urethra. It felt different from the other injects, not painful, just odd. I proceeded to leak my trimix from the urethra. That was a weird sensation! No harm though.

Ouch. I don't think I've hit my urethra, but I did hit a vein yesterday and it's pretty sore with a pretty decent hematoma. Just got careless. I usually take the time to pump up a bit before injecting, as it makes things much easier for me. But from time to time I go ahead and inject without pumping. I've had 2 misses this way, but no misses when I fluff up a bit in advance.

I appreciate everyone’s input. I have gained over 2” with fillers and the 1/2” won’t come close to hitting the spot. I have wasted an entire bottle of Trimix trying to make it work and it just won’t.

I did order some 30ga 1” needles which have me somewhat concerned… they are so long and thin that they seem a little flimsy and bend easily. I am nervous about it breaking off or something going wrong. Is this a valid concern??

When trying something quite different from your prescribed treatment, i'd check with a Dr first. I don't think anyone online would be able to answer your precise question about these longer needles, it's kinda impossible to know without seeing the things in "live" - the size of the needle, the size of your dick, anatomy etc...

If you’re going past 1/2” definitely discuss this with the doctor.

My pre implant girth was around 4 7/8”-5” flaccid and just over 6” erect. I used a 29 gauge 1/2” the entire time I injected. 5/16” wouldn’t get in the corpora. I wasn’t comfortable with a needle as flimsy as a 30 or 31 gauge.

Assuming you are exercising proper sanitary precautions I don’t think hitting the urethra would do much. The volume of medication is small. It might be an irritant, though.

I’m glad I’m not having to stick myself anymore, especially with a 1” 25 gauge.

Same happened to me last night. I am quite new to injections (this was my third) so I am still learning. I got a sharp panic attack when it happened because I knew somehow was wrong. I peed the injection solution (EDEX), which resulted in no erection at all, which was awkward to explain to the girl.
