I feel exactly the same way, same problem - don't feel like it at all when I go to bed at night, and if I do do it to make my bf happy, I ruin my sleep, I am exhausted ready to fall asleep before sex, but afterwards it can take me hours to fall asleep. Then I feel mad that I am not getting enough sleep and will be tired the next day.
I always feel in a mood early evening or in the middle of the day.
So you're not alone. Hope you can get your boyfriend adjust to you a bit more.
