Where has my sex drive gone? - I'm going to guess it's gone the same direction where your self esteem had vanished. A lot of times it would indicate a low self esteem. And if it's not then you don't find your husband sexually attractive any more. Do other guys turn you on? Why not taking a break and not see each other for a couple of weeks?

When I get married, my partner and I will be sleeping in separate rooms always. We will see each other only when we are well groomed and after shower. You spend every night with the same person for months and years, you see them drool, in the same underwear, untidy hair, bad morning breath, farts etc. and then we wonder where has the sex drive gone.

On the other hand, being a pan-sexual asexual or asexual pansexual I consider sex is only for procreation and occasional hot sex sessions when both partners are absolutely aroused. It is not normal for sex drive to be there between the same people for months and years, IT IS NORMAL and NATURAL for it to die out because this is how it is designed by nature - you have sex, then tend to your partner until they give birth and then men leave to find other partners to procreate. I'm not saying this is what people should do but understanding our genes and nature is crucial. So its ok to have sex when your first meet frequently but the longer you are together the longer should be periods between sex sessions. And the rest of the time you concentrate on knowing each other better, engaging in common activities i.e. enjoying life. People make mistake thinking if sex life is bad then everything else is ruined. Life doesn't revolve around sex, it supposed to be just a small, physical part of it, the rest is self development, improving your intellectual and creative abilities because this is what makes us human.
