My boyfriend and I have been together for over three years, and for the past few months, I feel completely unwanted by him. There's no major problem in our relationship other than this; I feel like I either have to initiate sex (and even then it's hesitant) or there's none at all, and I've asked him if there's anything special or different I could do to spark his interest. The answer is always no. I don't think sex is everything, but it is important to me and my self esteem takes a hit every time the topic comes up. I've tried letting things be to let him come around on his own, trying to be sexy for him, and talking to him. Nothing works. What can I do differently?
