Navigating feelings about marriage as a young Muslim girl

As-salamu alaykum. I’m a 17-year-old Muslim girl who’s always attended schools for girls until recently, when I started my final two years in a mixed setting. Honestly, I’ve never felt much interest in guys or experienced crushes like my friends often discuss. With marriage discussions becoming more common as I get older, I find myself really anxious about it. The idea of intimacy doesn’t appeal to me, and I worry I wouldn’t meet a husband’s expectations in that way. My family occasionally mentions marriage, and it makes me uncomfortable-I can’t imagine opening up to them about these feelings. I’ve also heard interpretations about marital duties that don’t sit right with me, and I believe a relationship should be based on mutual respect. Any advice on how to approach this would be appreciated, insha'Allah.
