Mismatched Sex Drives

My husband and I have been together for 4 years and married for 1. At the start of our relationship, in the honeymoon phase, we were very sexually active. This slowly (naturally) tapered off and for the last 2 years we have had a pretty infrequent sex life. The sex when we do have it is great, with no issues or problems. The problem for me is the in frequency of the sex. In opposites to general societal beliefs, my (female) sex drive is far higher than that of my husband's. we have talked about this really frankly and are both willing to compromise and meet half way but have agreed that we need to do research for both is us on how to increase/decrease our sex drives and desires. Has anyone else been in a similar situation and can offer some advice / hints / medication that worked for them? Thanks in advance!
