What are ways i can prevent utis every time i have sex? i try to have a full bladder before so i can urinate after but its difficult sometimes?

Postcoital UTI: Honeymoon cystitis is a term used to describe lower urinary tract infections in the bladder or urethra in women after vaginal intercourse. If this is a recurrent problem after every sexual encounter, we often prescribe a single dose of an appropriate antibacterial pill to be taken immediately after intercourse as an effective preventative measure. Discuss this with your physician or gynecologist
