never in the mood

I love sex, it feels great, my current bf is the only one to get me off or close to off consistently yet I seem to be never in the mood anymore! What can I do to hype myself up? Is it normal to feel this way?

He's 10 years older, I'm about 27 now. we were in a long distance relationship for a year and have been living together now for 5-6 months. in that first year, I wanted sex all the time when I was with him but only saw him for a week at a time every 3-4 months. since moving in together my sex drove went back to what it was before him: non-existent.
