I got a kidney infection last week and had bad fever. i took antibiotics and i am better. did this happen because of sex? is there a way to prevent?

UTI: You can get a UTI from having intercourse.Some ways to prevent it is to drink plenty of liquids, especially water, wipe from front to back, empty your bladder soon after intercourse and then drink a full glass of water to help flush bacteria, and avoid potentially irritating feminine products.If you notice a signs of a UTI get rid of it asap so it doesn't progress to your kidneys hope this helped :].
