This situation must be frustrating for you both given the length of time you've both been married and how long it appears that each of you have been suffering needlessly. I'm sure that you've both talked through this situation and tried to come up with a few compromises but perhaps to no avail - if you haven't expressed some of these thoughts to your partner it isn't a bad idea to bring it up. Communication in situations like these is paramount. Perhaps a first step might be to visit your doctor to rule out any medical reasons why this might be occurring - nothing wrong with getting a qualified medical opinion. If there aren't any medical reasons tied to this then perhaps @Topsy is right, a sexual therapist might be able to do some good for the both of you.
I think when we get married it's often thought as a natural process when the rings are exchanged that two people will see things similarly and have the same cravings, desires, and needs. I think for some couples, that reality slaps them pretty hard after the first two years of marriage. However, in your case 7! Perhaps your sex drive is different than his and that is a core issue - but between the medical verification and sexual therapy - perhaps there can be a bit of compromise between you both and maybe even a bit of peace when things even themselves out.
