Nothing you report strikes me as unusual. The first few times can be a bit uncomfortable as you exercise tissues that have gotten used to being inactive. The stretchy bits take a while to remember how to stretch. As you exercise your hydraulics they will tend to be more comfortable and work better.
Your question about
how you will react to a larger dose depends a bit on the details of your vasculature. If you have a venous leak then you will be less sensitive to increases in dosage and you will find that, as you say, your erections will last longer (since it takes longer for the blood flow to wash away the drugs) but you won't get much harder. On the other hand, men with good venocclusion can be very sensitive to dosage and a very small increase can cause the drugs to be trapped (along with the blood) so those men get a very hard, very long-lasting, and actually dangerous erection from just a smidge more than their correct dose. I think this happens less with bimix than with trimix (or straight alprostadil) but I am not sure.
That's why it's important to increase the dose slowly so you can avoid that trip to the emergency room. And once you find the right dose you should keep track of how long things stay at the ready, and think about
reducing your dose if you find that it is more than you need.
