Vagina now smells like boyfriend?

Im actually getting angry and want to know If this is a thing!!!. I feel like i am going crazy. I know everyone has a natural scent…sometimes down there smells like nothing or just vagina etc…. I do smell checks and recently it’s been smelling like my BFs natural scent?? Is this a thing?

I am like confused and going crazy. I go like 4 days without seeing my BF and I do a smell check and it smells slightly like HIM?.. is that a thing..
