So about a week ago I lost my virginity and I think I have a UTI? I use to get frequent UTI’s before hand but it's been almost 7 months since my last one. My friend had mentioned that after sex I should go to the bathroom to help avoid a UTI but I was unable to considering our surroundings. What is the easiest way to get rid of a UTI without going back on to antibiotics? I know water flushes the system but are there other remedies?
