How to deal with girls liking your boyfriend?

I’m black and Mexican and my boyfriend is white and Asian. Lots of girls like him and he’s so nice they may take it as flirting. He def likes me Cos I’m the first gf he’s brought around his family but it’s still frustrating and hard. I always feel ugly bc the girl that are on him are white white girls who look nothing like me so I feel like I don’t fit in...especially bc my boyfriend is more white looking...it’s just idek advice please. I need to be more secure with myself or not so jealous ig.
