Vagisil !

So I wanna start using Vagisil but my mom always said it messed with her PH balance. Well my best friends mom who is a little older said it’s really good for your vagina. She also told me douching is good for you so I don’t know how to feel. Can someone please tell me the truth about Vagisil? I’m 17, I’ve always had problems with odor and I’m not sexually actively but I’m getting closer to having sex each day. I wanna figure this problem out so I can finally have sex and put this issue to rest.
