Regarding the answer to the question about asking different Rabbis questions. Should one tell the rav that he might be asking around. If not, is it genavos daat? The Rav is thinking that your asking him the question. However, if you tell the Rav your intent he might not be willing to answer fully. Its not that your going shopping for lenient view points, you just want to hear what different poskim have say regarding this issue so that you can better follow a path suitable for you.
There is no need to inform the Rav of your intention. It is the Rav’s duty to answer the question, and the person asking has the right to ask somebody else, without having to inform the Rav. This is not a case of geneivas daas, because the question is sincere, and there is no falsehood or trickery involved.
