Urinary tract infection?

i get this ALL the time. your doing all the right things by taking the cranberry pills, cleaning etc [make sure your partner is cleaning too] but i found the most effective thing was making sure to pee STRAIGHT AFTER . as soon as you possibly can afterwards, even waiting for as short as 15 mins can be enough time for a UTI to start forming. and to answer your other questions no condoms and lubricants cant, although if you are using flavored ones or ones like durex 'tingle'they can cause irritation. durex have an aloe vera lube which is great because it is kind to skin and i found causes least irritation. hope i helped, thats all i can say to contribute really!
