I dont always feel appreciated in my relationship?

Does it matter how much I love and respect my boyfriend, how much I support him, how much I do for him, how much I work out to make sure I stay in shape so I can look good for him and for myself. I just want him to stop checking out other girls and drooling over them. He isn't perfect looking , he could use some improvements himself in the physical aspect of this, by the point is, I love him and respect him enough to always make sure he knows that I love and appreciate him in every way, and sometimes I just don't feel like he is matching me 100%. I just want it to work out but don't want to lose my confidence as a person or in this relationship. Any good advice?? Thank you.
