Hey Chihuahua, I just went through this and it was because I was going hypomanic. It does feel like you become a sex addict. I felt like a rabbit in heat and nothing could cure it. As soon as I was finished I wanted more and more and more. It is sad when it goes away because like your husband my husband feels the same way. It's like you become one with your partner and are totally in sync on that aspect of the relationship. Mine hasn't abruptly stopped but I feel it dwindling away.

I was open with my hubby about what I was going through. He just smiled as I talked because I went from not wanting it AT ALL to that, he wasn't going to complain. So long as you keep it in the relationship tell him to just enjoy himself while it lasts, you too. I was stupid and decided one man wasn't enough and it got me into some trouble at home, so best advice is to be completely open, unashamed and go with it
