will girls always care about sex more than guys

I really care about sex. My boyfriend and I were each other's first and that meant so much to me. I feel like if we broke up that would be the hardest thing for me to get over. It just means a lot to me and so does sex and I know it means a lot To my boyfriend too but I still feel like I'll always care about it more. Are girls always gonna care about sex/virginity more than guys are? Are we just built to be more emotional when it comes to physical stuff?
