i need help.

Hi. I am 20 years old. My boyfriend and I have been together for almost 5 years and there's a slight problem when we decide to have sex. My boyfriend has a high sex drive and I have a low one. I have a low one. Due to both the medication I take and the way I grew up. I grew up to believe that having sex before marriage is impure and it should not happen till marriage. I was wondering if there's anything I can do to try and increase my sex drive?
