My boyfriend's lack of sexual interest is making me feel "ugly"

Title. He seems so in love and he touches me all the time, but never iniciates sex and when I do it, he sometimes ignore it. I have always struggled to keep my self steem but lately I feel so... Rejected. I tried talking to him about it, twice. He says there is nothing wrong but I feel like I am not so attractive to him anymore. It hurts a lot because I never loved anyone like I love him. Anyone had a similar situation? What should I do? (Sorry for english)
