My penis is thin and 5/16 works in most places, but I get fewer misses in a few places using 1/2in. Apparently my corpora are not nice and straight and parallel like the medical diagrams. Keep a record of your injection parameters and you'll see a pattern after many injections. I suspect thicker pen...

I've used Trimix on vacations which had warmed to room temperature for four days, with no change in effectiveness. I've never frozen Trimix, but kept it refrigerated at 40F(4C) for as long as six months, again with no deterioration.

Hardonrescue: My wife and I are completely open about my ED, and she's patient with our lack of spontaneity because I have to inject. She knows that I participate in an impotence forum, but I have private computer and email accounts for FT and to research gifts for her. She is not sharp with compute...

Injecting can be painless, but not quick. I've never used an auto-injector because of the lack of control. My penis is thin enough so that I can use a 31 gauge needle (5/16in=8mm). This goes in a little easier than the 30 gauge needles. Guys with thicker penises probably need the half-inch needles. ...

Someguy: My urologist once told me that Cialis is a completely different chemical than Viagra. Maybe it will work for you.

Luckily there are three or more other PDE5s.

Sean: Your post gave me a thought. Here in USA we're the inheritors of Puritanism, which the English (Hi "Never Enough" :D ) sent us a long time ago. Some of us are thus sexually embarrassed by nudity and sexuality, maybe only subconsciously, maybe consciously. This nonsense is stuck in ou...

Norrr: Not all urologists are interested in our ED problems. Many are only interested in prostates and kidney stones, for example. A lot of FT guys have had to interview numerous urologists to find one who will take enough time to research complicated ED difficulties, some of which might have psycho...

Welcome to FT. I've injected for seven years once a week and have had no prostate problems.

Ha!

I need about 12% more Trimix in one side to get the same erection, so I'm guessing that this corpus has more volume. Both feel the same size though, flaccid or stiff.

Urologists say that testicles have nothing to do with the penis.
