Nokomis, welcome to the forums. There's a thread called "Getting to know you" where you can introduce yourself and say hi.
Now back to your question.
Have you tried the PI microsensor 3D shorts? I've got a pair of the ultrasensor shorts which I hate. I keep them for when I've been lazy and haven't done wash yet but I truly dislike them. After an hour and half to two hours they're just incredibly uncomfortable. However, I've not had this problem with the microsensor 3D shorts. Unfortunately the microsensor shorts are more expensive so purchasing a pair to see if they work for you isn't an inexpensive option but the chamois is (in my opinion) superior.
Performance also has a pair of shorts with a chamois that I personally found to be very comfortable. However my husband doesn't let me wear them unless I have something covering them. As he says they leave very little left to the imagination.That pair typically gets used during the rainy winter here since they're covered by my rain pants. I'll look at them later when I won't wake him to see if they have any labelling on them that state which shorts they are.
