BV thrush and UTIs

So I have BV Right now and I have literally JUST been treated for a UTI and finished the course of antibiotics a week and a half ago. Since I was a teenager (im 27 now) Iv had trouble with either a UTI, thrush and BV. It's so frustrating because I am not unclean! I only wash my intimate area with water and sometime use a bit of aqueous cream. And yet I just seem to end up with one of these problems!  It's so frustrating as its affecting my sex life with my SO. He is so understanding but I just feel like I am dirty and don't want to risk passing anything onto him. Does anyone have any advice because it sends me to tears some days? I just want to be normal and NOT have an intimate problem for more than just a couple of weeks x
