It's pretty much a certain thing that your physician or their staff is going to inquire with you about any symptoms or thoughts you have worth mentioning before your physical examination. That said, there might be some things that you've always kept inside due to the personal nature of them, thinking and/or knowing that they aren't really a risk to your health but more out of curiosity.
Can you honestly say that you have always revealed your questions to your doctor even if they are of a personal/sexual health nature ? Or do you continue to keep something to yourself ? I have a feeling there might be a mix of these answers due to the diverse interests of the forum, but don't know for sure.
