prepared downstairs

Recently I've been wanting to be sexually active (yes I am a virgin and no I'm not rushing things or anything like that ) but I've always been very insecure about things ...including my vagina . But I don't know the difference between a good smell and a bad smell . Like I know my vagina isn't gonna smell like cupcakes and rainbows because it's a vagina and I know when things do not feel or smell so fresh downstairs so like...how do I know that my downstairs area is prepared..basically ? Cause I know I have that discharge is something else too. Just how do I know that my downstairs area is good to go and I don't have to be worried about looking stupid with my partner ?
