Yeah i agree that after being together for a while the sex will naturally dwindle and everything else in our relationship is fine. We probably have sex about one a month at the moment, if i'm lucky and once a week would do me! Every relationship is different obviously but i think that two years is not long enough to go from having sex 3 times a week to once a month....i dont even want to imagine what it would be like 10 years down the line
