YoG

Hi My problem is that my gf has 0 libido. We've been together for 1 year and we always had sex 2-3 times a week Maximum. It's good, but I just don't feel her excitement. I'm always the one who start it, talk about it. We had many discussions, and she said that she doesn't really have sexual pulsions, she's also easily tired. I feel like I tried everything. I tried to tease her, be more distant, more affective, romantic, I make sure that she came every time... She told me that it wasn't my fault, that she had to work on it, but I feel like I don't turn her up or something like that. I really love her and I want both of us to enjoy our sexual life, but I don't feel satisfied. What should I do?
