Got urinary tract infections?
Do this: Ask your doctor about a preventive antibiotic. "I tell my patients who regularly get these infections to take an antibiotic after sex if there is an association between the infection and intercourse," Iglesia says. (But do not take the antibiotic more than once in a 24-hour period.)
Or this: Urinate both before and after sex, Iglesia suggests. Before, because bacteria around your urethra could be pushed up during intercourse; after, because you’ve got your partner’s germs to flush out also.
