Vagina smells like condom??

So I’m long story short, my boyfriend told me that my vagina smells like condom, which we’ve never used. He thought I was cheating but he apologized (I mean I would’ve thought that too) I’m just wondering if it’s normal? Because I took a shower the day before and for it to smell like that has me shook, I don’t know if it’s because I was too lazy to change my underwear 😂😂 or if I have infection... (disclaimer I did not cheat I’m 100% loyal)
