In summary, my girlfriend is very insecure about her body. She is a little heavier than the average girl but I like her body. Regardless, she is always very worried that I will see, want to look at, or openly stare at other girls with stereotypical attractive features (thin waists, plump butt, etc). We're going to a popular beach soon where I know many girls wear thong bikinis and other skimpy cheeky type things. I don't stare but it's hard not just to see this when it's right in front of me. How do I address my girlfriend's preoccupation with this? Me just saying that I only want and desire her has not really worked so far. Any ideas would be appreciated.
