I feel so desperate and disgusting

My fiancé and I got engaged four weeks ago. We had sex twice. He also made comments about how my hair looks weird one day after I got ready for our first date night. I bought this cute lingerie dress and asked him how it looked and he said nice. I started touching his dick this morning and he laughed and said it tickled. I feel so desperate and absolutely disgusting. I asked if he’s still attracted to me and he said yes. I asked if I need to go to the gym and he said I don’t have to change anything. I’m the same weight as I was when I met him, if anything I think I’ve gotten prettier as the years went on but I don’t feel it inside. I feel DISGUSTING. I want him to have that animalistic drive and passion for me like he used to. I feel like he’s just not really seeing me anymore. When he grabs my boobs or butt, it’s usually as a joke and for a silly reason.
