Point her in the direction of this thread:

Maybe just say, I really love spending time with you and don't want to stop coming to see you, but I was wondering if you might take a look at this, because maybe your pH is off or something else is wrong.
Or if you know her well enough, send her a box of the gel as a hint, or drop a box off on her front steps in a box. lol
But also, every time you go to see her, take a shower with her when you get there. Wash her up and down.. make it sexy and fun.
