my cum smells weird😳

this is so embarrassinggggggggg BUT I need to know. so I dont finger myself often but when I do I smell my fingers after out of curiosity. and they’ve smelled the same way since i’ve started (maybe 3 years). my cum/vagina doesn’t smell fishy or anything like that. it’s just a weird smell almost like (idk how to describe it) pennies? like a light metallic smell. idk if that’s just how vaginas smell or if mine is weird. how do I change this bc i’m i’m highschool but haven’t hooked up with a guy yet and when I do I dont want him to smell this bc it’s not like ew her pussy stank but it’s not appealing. i’d rather it smell like nothing. I tried cranberry gummies bc cranberry supplements are supposed to make it smell/taste better but that didn’t do anything. so any tips to make it smell better or different or am I just stuck with this? plz lmk😭😭😭 thanks
