Low sex drive

Esther
So I've noticed that a lot of girl talk about sex , sex, sex and I don't think is bad , but is there anyone out there who's sex drive isn't as crazy? I'm in my early 20's , I have a loving boyfriend whom I adore and he's soo good in bed , but my sex drive is very low ! I don't have the energy to want to get it on, I've done a lot of reading, I tried different things but I cannot figure it out! I just want to know if anyone else had to deal with this because it has been driving me insane. My mom thinks I have a thyroid problem for other reasons but I feel like I'm too young for that. Any suggestions would help.
