I know where you are coming from. My fiance and I have been together for 6 years now, and in the first two years we had sex often - but I always initiated. After that I started initiating less and less - fast forward to now, we only have sex every 4 months or so, which I initiate. Did it bother me yes? Very much.

But in my case I realized I kept minimizing and even ignoring why he didn't initiate or want sex. I knew why, but that wasn't so important to me. The only important thing to me was that we weren't having sex.

He has GHD and more estrogen than testosterone. He pretty much has no sex drive as a result. On top of that, he doesn't last too terribly long in bed and this kills him and I final,y realized it left him very embarrassed and ashamed after sex. That also turned him away from sex.

Today I have accepted it and we still have an excellent relationship. He says he loves me and calls me beautiful every day. We kiss and hug and cuddle every day. We play around and laugh together. We binge watch our favorite shows, play videogames, and go out when we can. He's hard working, loyal, and intelligent. He's my best friend and the love of my life and we dream of our future together.

If your husband wont have sex, it would probably help you to get to the bottom of the real reasons why. Being tired is pretty vague. Plenty of people have sex when they are generally tired from work and such. Being tired is the effect of something, and the cause is what needs to be modified or fixed so he is not always feeling so low. Mental exhaustion is generally caused from too much stress. Is there any way he can simplify his life and find more time to be away from stressors?

Also, if he's not having sex with you he should atleast be showing that he adores you and pursues your love in other ways every day. I'm not saying not having sex is ok, what is ok and not ok depends on you and your needs. But for now, until he's better, affection and adoration from him could help give you the patience for him to get better.
