Lou,
What has she done, so far, to reduce the UTI's?

I can't remember what you said about the pee-sex-pee routine; does she do this? This helps me a lot, though I still get them occasionally.
Does she drink cranberry juice and, if not, PLENTY of water?

I don't know what to say about the FC's. I am an HD woman so the smells and fluids of sex don't bother me and I actually like them.
All I can say about the smell is to shower the next morning and go on with life. It doesn't last forever, right!

good luck, Lou.
