He treats me so well

I am so insecure and I never feel good enough for my boyfriend and he never plays mind games with me. He always tells me that he is here and he isn't going anywhere. Ive known him since 5th grade and we are now 16 (almost 17) and we have been dating for 2 years. I lost my virginity to him a year ago and he's never made our relationship only about sex. If I feel very insecure and don't want to show him my body he cuddles me and massages my back instead. He is 16 and talks about us having a future together and he's the most loyal young man I've ever met. He makes me a priority and I'm beyond lucky to have him as my friend and boyfriend.
