mines purple, glittery and flashes in the dark!!
But seriously and this might be quite wrong but I remember when Alex was first diagnosed, I rang a friend overseas who had suffered OC 7 years before. One of the things he said whilst he was warning me of all the potential disasters about to befall us, was that Alex and I would never again enjoy deep and passionate kisses. At the time I was much more concerned with keeping Alex alive so didn't take any notice at the time. I vaguely recall he connected it to the loss of saliva...
Now I read this post, and wonder if there is something that is bothering your husband around lack of saliva or even taste?
Of course it is also likely that your husband is fearful of "catching"
HPV again - even though this is illogical.
I have a mortal terror of being a passenger in a reversing car due to an accident I had when I was a kid. I know that this is illogical but that knowledge doesn't help me much when the palpitations start. Maybe your husband is going through the same thing? He knows it is illogical but needs time to deal with or get over the fear?
