I didn't even know what HB was, but we clearly had it.
My wife was afraid I was going to leave, and sex was reassuring to her. She wanted it, because she needed reassurance. I wanted it because I wanted sex, and I liked and loved her. In fact it was during a night in a hotel room, on the 18th anniversary of our first date, when I had been trying to get her in the mood, unsuccessfully, that she confessed.
HB was messy emotionally...but then I was so emotionally disturbed by it all that it could not be otherwise.
