Hello! First post and looking for some advice, or at least sympathy

My boyfriend and I have been dating for over a year now and have been sexually active since the beginning. During the first few months we had sex very often, multiple times a week. After about four months with him and after years of going without a yeast infection, I got one. I absolutely HATE OTC treatments, they seem to just aggravate the little yeasty baddies and they come on ten times stronger than in the beginning. So I looked to "alternative medicine". I tried yogurt (orally and topically) and even garlic as a suppository. Those seemed to hold them off for a little while, but never permanently. So I took the Diflucan pill and it disappeared like magic!

Alas, my time of peace did not last long. A few months later it was back. And again, Diflucan came to my rescue. Since then I've had a few "scares," meaning that I'll get that dry, uncomfortable feeling that always coincides with the yeasties, followed by some itchiness and slight cottage cheesing, but it appears fall back after a day or two.

So you may be wondering where my boyfriend comes into this picture. After the first few infections and scares I started making a connection to intercourse (we seldom use a condom, I'm on the pill) and the yeast problem because many times when we have sex I start to show symptoms shortly after. This is a problem for two reasons: a.) It causes me to be very apprehensive about having sex because I am beginning to associate it with the yeasties and b.) I'm getting !@#&@ing yeast infections!

I know that yeast infections can be caused by many different things, but does anyone else have a problem that relates? Any advice? I'm making an appointment with the Gyno tomorrow but I don't have too much faith in this situation.
