My (26M) chubby gf (24F) has always been self conscious about her body, how do I help?

We've been dating for about 2 months and I really like her, which is why I want to help her with her insecurities. I want her to feel confident in her body, I love chubby women, I think they are really hot and I just want my gf to know that I love and appreciate her the way she is. I can tell she always struggles with body dysmorphia and I want her to be able to feel confident in herself. A few ways I have tried to help her is by making sure she knows I find her attractive. I give her lots of compliments on her body and I'm always telling her how cute and sexy she is, but I feel like it's not getting through to her. I've tried giving her massages and getting her to relax and I'm just not sure what else to do. I really want her to know that I love her the way she is and I just want her to feel confident in herself. I think she's really cute and I want her to know that. Has anyone else had this experience? How did you help your partner?
