Hi Ricky,
Yes it can be an ominous experience at first, but you will get the process down pretty soon. a jump of .10 is a huge jump, you may only need a few more units to get you to 100% or just a post injection hold of the medicine in the penis
I found that the injection was most effective if I held the base of the penis tight with my left hand while injecting ( with auto injector) with my right. Then after the injection, press and massage the area with the wipe for approx 60 seconds, it helps distribute the medication before the blood flow flushes it out
Try to get 30 or 31 gauge needles they are a bit smaller than 28's and much thinner than 26's
Here is a BD auto injector that I have been using for months and it works perfect, just aim and click
