Libido problems

Clover
So I don't usually like to post on places like this but I do have a little problem and maybe you ladies can help me out. 
I have a sex drive problem. Which is weird because I /want/ to want sex, but I just don't. And my lover is never pushy or expectant, he never pushes me if he even has the slightest fear that it would make me uncomfortable.
But like, I just never seem to be in the mood. Or... I'm always in the mood and sex is all I think about and I become addicted to porn. Like, there is no middle ground for me.
I have a weird and complicated relationship with sex, but all I want is to just have it like they do in movies where they get all snuggly and bam they're banging. But I just never seem down for it.
What's wrong with me? Is there anything I can do to fix this?
