Here's the deal I have been with my partner for a long time and I get the impression DW would like less sex than me as apparently I want it all the time (which is not true). What i am trying to understand is at what length of time in a relationship should the sexual desire of a couple dwindle to near extinction? I do not want to become a couple who only have sex once a month as I am highly driven in that department. DW is a stunning woman who works hard at keeping herself in tone and has lost a significant amount of weight and I worry sometimes that maybe I am no longer fully satisfying her or she has a new impression of herself to which I am not up to standard. If there is anybody on here with advice because I feel like I am the bad guy for wanting relations to which is a very natural instinct.
