Nelson Vergel that was the only time trimix didn't work well for me. I'm thinking I may have missed my shot a little because for days after that shot my penis was kind of sore all over. Not bad but a little sore. It did work but not like it normally does like last night. Last night I made sure I hit the correct area and made sure I emptied the syringe of .2 ml and it worked perfectly so I'm glad I didn't up my dosage any. I read that if I'm to flaccid I could miss the corpus cavernosa because of it wrinkling up so much and I believe that may have happen then. This time I made sure I wasn't that flaccid. While getting the medicine ready I kind of get nervous so that doesn't help any. lol
