Man, I used to get them all the time, even low grade ones. Unfortunately I know all about this topic...I got an earful from the the doctor at the clinic while I was in college...
The other ladies are right. Sugar and caffeine aggravate UTI's. Getting dehydrated aggravates UTI's. Yes, drinking lots of water helps.
Having sex does not though.
Since we can't all be chaste, there are some steps you have to take to prevent UTI's, as unpleasant as it seems. The reason for getting UTI's is threefold. First of all, when you're having sex, more often than not, you're bruising your bladder, which irritates the lining of your bladder and tissues. It sounds Dr. Ruth-ish, but try being on top or some other position than missionary.
Even if you don't do any of that, clean yourself after sex and pee. This will flush out the bacteria from the bladder (the bacteria coming from you and your partner which is currently sticking to your urethra). Be sure to wipe front to back. E-coli from the perianal area causes UTI's as well.
Secondly, you and your partner can exchange yeast and bacteria back and forth which further aggravate UTI's. Try to get your partner to do a better job of washing up and/or give him some anti-yeast/fungal ointment as well. The folds of skin on the penis harbors all kinds of yeast and bacteria.
Third, the infection stays and can get resistant to antibiotics. If you are in dire straights, try the over the counter medication for UTI's (UZO is good), but other than that, keep doing the cranberry extract. Is that the same as cranberry pills? The regular cranberry pills from the drug store are horsepills. You have to take a couple of horsepills worth of the cranberry pills and flush it down with LOTS of water to mimic having a few glasses of cranberry juice. If you're taking the little gelcaps of cranberry juice extract (powdered cranberry juice), you have to take like 3 or more for it to work. 3 like several times a day.
As with yeast infections, keeping the vagina area dry is good. After showering, take a blow dryer on cool to warm heat and dry the area, including the perianal area. Cool, dry, clean underwear with a cotton lining is always a plus.
What I do these days is pop some cranberry juice pills (Juice Plus pills are great, it has acidophilus in it already; I take the cranberry and other juice extract) right after sex. I pee and clean myself up and do whatever I need to. I have explained to my significant other that I'm not trying to kill the mood or anything, but it's nicer to come to bed clean and refreshed and so that I will not be sick with an infection in the morning. He understands.
In the morning, I may even pop a few apple cider vinegar pills or drink 2 teaspoons with lots of water. I do this when I feel discomfort when urinating, even when there has not been any sex involved. Summer is bad for UTI's regardless of intercourse. Sometimes not drinking enough water, drinking soda or something with caffeine, and general stress will do it. The apple cider vinegar pills help balance the yeast AND kill any bad bacteria. It helps flush the kidneys as well.
Don't let UTI's go too far. The bacteria travels from the urethra into your bladder, up the ureters and into your kidneys. Once you have a kidney infection, that's just bad, bad news.
Take some tylenol for standard UTI discomfort.
