Different smell?

Ok idk if anyone else has this happen to them, but there’s obviously a smell down there (not like super bad, but all ya’ll know there is one) and I personally know my own smell? Lol. But whenever I have sex with my man, for the next couple of days my scent will change and I can smell his? Does any of this make sense? Like idk of his will still be in me or if it just makes my body chemistry change, but it’ll smell like him and me for a few days. (Disclaimer; I also have the nose of a bloodhound)
