How can I stop feeling inferior to my girlfriend and her brother?

I feel inadequate when next to them, because they are tall, blonde and with blue eyes. I'm short and with brown hair and eyes.
They both adore me and my girlfriend jokes that sometimes she has to contend with her brother for my attention.
I admit that I enjoy being so mollycoddled by both of them, but sometimes I can't help but feel conscious for my appearance compared to theirs.

I realize they are from a superior genetic stock, but I can improve and prove myself worthy of them damn it.
