Is this true?

Maybe I’m crazy but I thought that once you have sex w a guy it changes ur PH a little and that can make ur pussy smell different?

Cuz I have had sex but he uses lube and the precum gets there and since then mine I can tell is weird. Like it’s not a yeast infection but it feels like it could be the start of one.

That could be the lube we use but mine just smells bad easily even when I take care of it, it’ll only last like half a day - a day and it’ll kinda smell again. Yes you are suppose to wash it at least once a day and I do but I don’t think it would start kinda smelling not so nice by the time I go to wash again so soon
