My Vagina

Okay so about two days ago my boyfriend and i was in the shower, so we showered, got out and laid on the bed. He went down on me with the vibrator and kind of ate me out, after i had my orgasm he came up and kissed me. As i was kissing him i smelled a smell and it smelled like musk. Now i had just washed my vagina with summers eve and it didn’t smell before we started so im thinking maybe that’s just my natural scent. That’s not the first time i smelled it either, i have smelled it other times when we would get a little intimate. He never complains about the smell but sometimes i get self conscious about it because i dont like it. Sometimes i think its all in my head lol but i dont know. Is anyone else having this problem? I would love some advice on how to fix it.
