Mazal tov on your recent marriage!
The rules of appropriate sexual behavior are not completely spelled out in halacha. There are proscriptions in the Talmud which some authorities view as binding and others view simply as advice. Being intimate during the daytime falls into this category. Some frown on relations during the daytime, while others view it as fully permissible as long as the room is darkened. There is no clear-cut right or wrong in this situation. Additionally, as long as Kriat Shema is said in its proper time, there is no halachic issue of being intimate in the morning before Shacharit. The two of you have to communicate with each other about your concerns and come to a mutual consensus.
However, it is very important in the beginning of marriage to strengthen the ties of your marriage and your shalom bayit, and intimacy is a very powerful way of doing so. Taking on stringent practices may have inherent positive value, but not if they come at the expense of shalom bayit. We do not recommend adopting stringencies in your intimate life at this stage in your marriage, especially if one of the members of the couple does not wish to do so. Expressing your love to your spouse and giving each other pleasure builds an emotional and spiritual connection between the two of you and that is a profound way of creating kedusha and tahara in your marriage.
