Confused and disappointed

Hi ladies,

As I am lying in bed writing this, I am feeling down about myself. Lately, I have been struggling with my weight and don’t feel attractive anymore. My fiancé and I have always had a great relationship and he frequently compliments me, so no issues there. However, recently, I have been noticing a disconnect in the “sex” department. He always wants to be the receiver (meaning I blow him) and hasn’t initiated sex in over two weeks. I wish he would reciprocate and show more physical attraction towards me (touching, playing). I always struggle with telling him how I feel and what I need sexually in order to be happy. I know he’s not cheating on me but any advice on how I can approach this topic? Or initiate sex in a way that both of us will end up happy?
