This is internalized misogyny. Someone would only have that smell if they had an infection or other strong smells come from poor hygiene which is not related to sex specifically. Also, not like you’re going to know about it said smell unless you’re down there in someone else’s businesses. It is really not okay to let these sexist and nonfactual thoughts permeate to the point where you dislike yourself or are hateful towards women. I would see a therapist, and if you are around people who speak about women this way I would see them to the door.
