I need opinions/ideas?

I have been getting a bacteria infection more often than not ? Its very embarrassing and makes me feel like I'm not clean. I have started showering 3 times a day but I never feel any cleaner down there. My OBGYN gave me cream to help but after it goes away, its back in 2 to 3 months. Any ideas on how to prevent a bacteria infection or at least help with one because im spending alot going to the OB. Open to ideas or thoughts? Thanks in advance.
