Can my sex partner give me a uti if he eats too much spicy foods?

Your reproductive system, including your vagina, is totally separate from your urinary system. What he eats should have no effect on your bladder, etc. to cause a uti.

Getting fecal matter any where near your urethra can cause a UTI. This is a common cause if you are wiping the wrong way.

NO, your b/f eating spicy foods will not cause a UTI?

Why, do you have one ?
