I love her to bits. Why is it so wrong to just want sex with her for the sheer sake of I fancy you, you're my partner, I'm turned on.

But it's got to the point now it's always on my mind "when are we going to sleep together again next?" "What can I do to make it happen" and then in the end I keep suggesting it almost as a hint or a reminder, which then decreases the chance of sex so then I get even more frustrated which affects me emotionally which she then finds unnatractive
