I don't think there should be anything that causes embarrassment between a loving couple. It used to annoy me when I discovered my ex-wife kept a problem to herself, and it then grew, but I had the solution all along. If only she wasn't embarrassed to ask, or even confide in me. (I must admit, most of these were work related, and were to do with computers. I used to train people, but she refused to seek my advice.)
This has a habbit of spreading to other areas of the relationship, and should be nipped in the bud. Share everything. - Scorpios, I know this is particularly difficult for you, but please try!
