You *both* need to be tested if you have had unprotected sex. The procss is really very simple.
I went to my local hospital and had it done anonymously. It really is as simple as that. You might want to call ahead depending on where you live. If you live in a metropolitan area, they may do it at the health department, etc.
In my situation, I had my results sent back to my doctor. It took, if I recall correctly, about 7-10 days, but that was about four years ago.
About your wife's utis, there are a *lot* of things that can cause that in a woman. Our *equipment* makes it a lot easier for us to get those type of infections. There is even a name for women having a lot of utis.
Good luck,
