Has your man ever made your vag smell ?🥴

Okay my hooha has never given off an odor. It’s usually odorless and pretty tasteless too. I started dating someone 3.5 weeks ago and ever since we slept together the first time, I noticed the very next day (after my shower I should add) that I had a very strong very bad smell. It lingered for a day or two then went away. But now I’ve noticed that the smell comes and goes and is always worse in the day following our sex. Neither of us have STDs . He isn’t circumcised but always showers before coming over and never tastes bad to me .

Has this happened to anyone before? I’m starting to feel self conscious about this odor. Especially because he loves giving me oral and I don’t want him thinking I’m always going to be smelling or tasting like this 🙄. Like this is not normal for me but he wouldn’t know that and Idk how to manage it since I’ve never had this happen.
