Yes, it will take courage which is addressed by contemplating on why he will be doing this. He does need this to help of Trimix bring both of you closer to one another. Difficult? No, only in the mind. I faced it and moved on. Experimenting with dosage will take an effort and what will help I believe is to keep a continual record for each injection, date difficulty/success and then begin to zero in on what is right for both of you. I praise the Trimix as it is the only erection that I can attain every three days. The VED is OK for pump up for me but that is about it . We love my erections and count on them. Do I get one every time? NO. Sometimes you miss and suck it up and try another variety of sex in your soon to be developed bag of tricks. My injections are about 99% successful.
I found that my right side was a little more painful to the injections and I wanted to get rid of that situation. My PA told me to inject only on the left side. This is a no-no. One must not only alternate sides, but inject in the upper, middle lower part of the penis in rotation from injection to injection. Thus the log book becomes important to remember where you were at last. To aleviate my situation of pain on the penis right side, I purchased an BD auto-injector ($18.00) at Walgreens and fell in love with it. Use your normal injection syringe with 1/2" needle, load it into the auto-injector, locate where you want to inject and simply push a buton and its over. Might be a sissy approach, but its nice and no shaking hands in my case. The shots to me now are almost second nature - just need to miss the veins. Missing the visible veins is simple and is a matter of moving the penile skin forward or back. Also important, use alchohol pads to clean the rubber cover on the prescription bottle before taking the serum with the syringe, rub the penis with the alchohol pad at the area where the injection is to take place and then press firmly at the injection site with alchohol pad in place for at least five minutes - this will help eliminate plaque buildup down the road.
My system is currently comfortable with 0.06cc which gives me a satisfactory firm erection (80% or so). I always remind my wife when the injection is due so she knows when I will have an erection - use it or not. Based on our present situation, I inject myself 30 minutes before any action and as we get into foreplay the erection fully developes and can last up to two hours from there comfortably.
For experimentation, begin with a low dose, stimulate the penis alone or with another and monitor the result. If it is too much, at 2-1/2 hours take two Sudafed @ 30mg each and do some form of exercise (walk, up & down stairs, etc.). If the erection does not begin to subside at about 40 minutes later, use an ice pack (ouch!) against the penis. This should work, iF not call the Doc or exchange. If the dose is too low, little erection, that's OK. Up the next dose by 0.05cc only and patiently await the result. All will be well. Take things in moderation. The Trimix will be good for both of you.
Welcome back to male erections! A great feeling and satisfaction for us men, and I think for our wives also.
Anything else I can offer? Let us know how it goes.
