False.
UTI requires antibiotics. Pure cranberry juice can help prevent bacteria build but IS NOT 100 percent accurate, nor does it cure a UTI.
You can at first drink a TON of water and pure cranberry juice (no sugar added), and try to flush out the UTI. Sometimes it can work, but often you need antibiotics to kill the infection.
As your daily routine, yes, sure, take cranberry pills to prevent bacteria build up. Again, it's not 100 percent that it will do anything. Also, always go pee after sex. Maybe invest in wipes so that you can clean yourself down there after intercourse as well. Females have a shorter urethra, and so we can get UTI's a lot easier. Be weary if you are into anal play, that you don't go straight back to vaginal stimulation. It's a common error people make, and then they end up getting a UTI.
Did you get a PT and was it positive?
Just concerned about the issues you mentioned.
