I REALLY CAN'T HELP YOU WITH THIS BUT HAVE YOU BEEN TO THE DOCTOR TO SEEK HELP OR YOU CAN TRY USING,SOMETHING SWEET  TO SEE IF IT WORKS.JACKIE

I found that very interesting. Pineapple I haven't experienced yet but I learned years ago when I dated a man who drank grafefruit juice daily how yummy it tasted. I believe it's the citrus fruits that work & make us/them taste better. Fruit lovers are my favorite males to taste!!

It's something in your diet or if you take a lot of viatamins.

Regarding the 'taste' your husband doesn't exactly care for with oral sex.....try drinking pineapple juice daily.  I have heard that will make you more 'fruity' down there.  I begin drinking it a couple days before I know that could be a possibility and I have had no complaints.  But the metallic part just might bring me to my doctor.  Good luck!!
