How do I take my sex drive down?

I’m a lesbian, and I’m in a relationship currently. Well, it seems that every single night I get in the “mood” to do things. But my girlfriend of course doesn’t want to have sex every night. I’m not going to ask her to do something she doesn’t want to do. And I hate that I’m horny almost 24/7. How do I make this stop? Or at least slow it down?
