Girls onyl, do you enjoy often?

I am in shape and good looking, Yet my girlfriend is very seldom in the mood. I know she loves me very much. She does so many things for me and is always there for any other need of mine. I want to know if you girls want often or if you can do without it which my girlfriend obviously can. I am 27 and always in the mood for which she isn't. Besides this, our relationship is GREAT. please, any info?
