Mine went completely for a long while, and I was very upset about it as I've always been quite highly-sexed (sorry if tmi).
Am mildly embarrassed to admit this, but.....
a good long hard wank, even though I wasn't really in the mood (I believe someone in a book somewhere called it a 'bully wank'), several of them on separate nights kind of got things flowing a little bit, then after a month or so it just kind of clicked back into place. Now I'm as horny as I ever was (poor DH).
I had to really make myself make the effort, iyswim, I wouldn't have done had I not been distressed at what was (to me) an important part of my life just vanishing into thin air. I had zero sexual feelings, no desire for anything but sleep and it alarmed me.
*lovecat' very bold and honest of you and I agree and think it also gets things 'flowing'. It's all to do with 'hormones' and I reckon that every now and then things get dormant and need waking up at our own pace. Good honest remedy!
