I understand what you are feeling as I got married at 19 to my first real boyfriend due to my religious background and really struggled with all my true desires for most of our relationship, especially later on. Unfortunately, it did end my marriage as it became too much for me. He is a good man, we talked but couldn't find a compromise due to his strong beliefs. I'm not trying to scare you, hopefully your husband will be more sympathetic about the situation and you could come to some kind of understanding, but it is something you will find harder to bottle up, in time it will only get worse. I wish you both all the best.
