No Sex drive putting strain on marriage

I’m 23 and have been married for two years and lately sex has been feeling like another chore to get done. I feel bad for my husband because he has a very high sex drive and I feel like it’s putting a strain on our marriage. He knows I have a low libido, so most of the time he doesn’t even try to pursue anything. I am still very attracted to my husband, it’s just that I have no desire at all and I don’t know how to get it back. I miss having that connection with him. I am on birth control pills (sprintec), but can it cause a nonexistent sex drive? I live a very active lifestyle, I exercise, I eat healthy, and I’m not really stressed about anything. Is anybody else going through the same thing? What can I do to get my sex drive back? Any comments are greatly appreciated. Thank you.
