S.P.
What your doc said is the truth. Me, my sisters and my mother are all just prone to them. I go through all the same things where sex is concerned with my hubby. It's a pain and it's just a shot in the dark as to whether it will keep it away or not. I pretty much know that if I have sex I have a possibility of getting one. I hate the UTIs too but I think I've just learned to live with it. One thing that I did have a doc do was to give me a script for an antibiotic in a low dose that I could take before having sex, or shortly after, that would try to ward off any potential bacteria/infections. I would have used it if I hadn't been breastfeeding at he time b/c it gave irritated my little one's digestive track but it makes sense and I am totally NOT a medicine person but have learned that this is one thing that I have to take antibiotics for b/c it never goes away on it's own and always seems to strike at the most inconvenient times (i.e. on a weekend or before a trip out of town.)
