Out, Out Damn UTI!

Could not cleaning myself a certain way after sex be causing my frequent urinary tract infections? What is the proper way to clean myself after sex (we use condoms and KY)?...

I think I have a UTI: what should I do?

I am a teenager and think I may have UI and that could be from a UTI but what should I do to treat it/make it go away as it is affecting daily routine? I have not visited any doctor as I am embarrassed to tell my parents about this possible problem. Do I need to see a doctor, if so how should I tell about this condition to my parents as I can't go on my own?...

Is hand washing really necessary?

Is it a valid concern to be worried about my boyfriend washing his hands before he fingers me? I know he should if he has semen or pre-cum on his hands, but as a guy he hardly washes his hands. You know how some guys are and if I tell him he still won't do it. Could I get infections or could he spread germs that have been on his hands this way?...
