You wouldn't be normal if you weren't nervous. Tri-mix has a very high success rate and you have every right to expect things to go well. Don't be disappointed if it takes you a few uses to feel comfortable with it. You may want to keep some benadryl or another antihistamine handy to help reduce your erection when no longer needed. Just a minimal recommended dose of Benadryl is needed to bring things back to normal. I can usually count on a 3 1/2 to 4 hour erection which borders on a dangerous length of time. Also, it can get painful after a time. I have found backing off the original prescribed amount about 5-10% is my sweet spot...effective and wearing off in less than 4 hours. Also, I've found I need 15-30 minutes to reach full effectiveness, not the 10 minutes I had been told would be likely. With a little practice, I think you'll be glad you tried it. Hope to hear a good report.
