I've been with my fiance for almost 6 years, we have a 5 year old together. I know he loves me and wants to be with me but the spark is gone. Every once in a while we will get it back but it doesn't last more then a day or two. I've told him and even written him letters to express how I feel about him and that I want more of him, more kisses more touching, MORE SEX, it doesn't happen. I've even tried planning sex and doing something he likes even if I dont like doing it. My goal is to get him back into the mood, every day not once a month or longer. I dont know what else to do I need help.
