He doesn't want to make love to me anymore

My husband used to want it two times a day if not more. Over the last three months we have made love three times. I'm the one who initiated two of those times. I have asked what is going on and tried to figure it out and I just don't get it. I have not gained any weight I dress in sexy clothing. I have asked if there is another woman and he has told me no. He says he loves me and that there is nothing wrong with me, but I feel like I'm not doing it for him anymore. We have been married for almost 15 years. I don't know what to think or do, what is my next step? Tweet
