(Cis female here) aw, hun, that’s rough. I feel for you.
I don’t know if this is the same for anyone else, but I find the less I have sex, the less I want it. This can become a vicious cycle (and it’s why I’m crap at long distance relationships. They flip my ‘ off’ button). Once ‘off’ it takes me considerable time and perseverance to develop any interest again.
On the other hand, the more sex I have, the more I want it. At the moment OH is having difficulty keeping up, and LH has been a godsend (I don’t want to be a pest!)
OH and I also have mismatched sleep patterns which doesn’t help (I used to joke that we lived in the same house, but different time zones). What worked for us was focusing on morning/afternoon sex so that neither of us felt too knackered/sleepy for sex.
Libido can be a real rollercoaster of a ride for any kind of relationship. If your OH is in a valley and you’re not, it’s hard not to feel resentment but if you keep talking and are completely honest with each other about how you both feel, you can get through it.
