Sex drive

So ladies, when my man and I got together, our sex life was amazing.... Like one to brag about. It's still amazing, he is the best in bed I've ever had... But for some reason, my sex drive isn't as high as it use to be. We still have sex like once a day, most of the time.. But we use to way more. I really enjoyed it!!!! My sex drive is just meh lately and I'm looking for some natural ways to enhance it.
