<human>: Sorry if this is the wrong subreddit. Im also posting this to r/sex just in case. Lets get started!

Well me and my girlfriend of 3 years are both 18. I find her very very attractive from her head to toes. I could go on all day on how gorgeous she is. I get myself self caught up by thinking about her all day in class and at work. I compliment her all the time you could even say constantly. The thing is that when i do compliment her she says "I look ok". When she says that I can't help but be thrown off. I even got mad a few times we she said it cause that's how perfect i think she is. I told her how i felt and we talked about a few times and we talked about why she says it but it keeps happening. 
 My question is am i being to childish(lack of better word) by getting upset that she doesn't see her true beauty like I do? If not what can i do to help her see her true beauty?

Can you provide a brief overview of the text?
