sex drive

So I'm 22 and i have a very small sex drive. I used to be able to go 2-3 times a night, but now I don't want it at all. I feel like it is putting a strain on mine and my partners relationship, but he reassures me that it's not. I love him to death, I just want the sex drive to be there. I'm not on any forums of medication (contraception included) I came off it because I thought that was the reason. It helped a bit but not enough. The only contraception that gave me a good sex drive was the bar, but I got thrush, and my periods were all over the place so I got it taken out
