When i first started injecting and for quite a while after (years) i used to get a very distinct "metallic" taste in my mouth while injecting Edex, a bit like what blood tends to taste. It lasted for very shot while during the injection and was somewhat related to the results - If the injection was good, i'd get the taste. If i didn't get it, the erection would be mediocre.
Lately i've practically lost that feeling completely. I didn't pay much attention to it, but considering that the injection quality has diminished as well, i am pondering if it's not related.
Has anyone here experienced similar sensation while injecting? Has it evolved during the years? Or am i just a weird one?

40 years old, married. ED all my life because of spinal cord injury caused by a tumor in early infant age. Using standard EDEX20 since 2007. Increasingly bad results with EDEX in the last few years, but had very good results for at least 10 years.
