Does anyone on here do their own AI? I have now seen this done about 15 times and am getting play by play instructions from the men that are performing it. Do you have to go to a class to learn this? So far I think I know that you are feeling for the cervix and the straw has to go through the cervix just to the end and then shoot. The cervix is rigid and they are all not the same size. Am I right on any of this?
