Can a sexless marriage lead to a divorce?

Overall I have a great marriage but when it comes to our sex life there's just no passion or spark. It always feels forced on my end. Our sex drive is never synchronized. When he's in the mood I'm not. I enjoy certain things he doesn't and will not pick up the effort to do. The first year of getting to know each other was great and we got married after that one year but here's our second year in and I'm completely unhappy in this particular area, and sex is vital for me. At this rate of once a month cheating is a never ending thought and it's difficult to fight considering how much I love my husband. How will this end? Will I have to sacrifice this need and forever hold this frustration inside of me as I fight these never ending desires of cheating to meet these needs or is this a reason to divorce ?
