Why does my upper lip stick our further than my bottom lip does and is it a reason for other issues? (photos)

I know that it is not a problem with my bottom jaw. However, from a front view my top lip is larger than my bottom lip. From a profile view, my top lip sticks out noticeably further than my bottom lip does. Is this an issue due to my teeth? And can this be corrected? (Is this also why I have speech problems pronouncing my R's?)
