"One advice for you:keep the tanks full at all times". Obvious statement, but easier said than done.
Seriously: "One way or the other,sooner or later SEX must be discussed with her. Unless you are only venting here it seems that it affects you a lot. Maybe not the time yet but you know you will have to". Yes W and I will need to talk and now is probably not the time. Whenever I have tried to broach this subject in the past, her responses have been very defensive, things like..
"Is that all you ever think about....."
"Yes we need to talk" (then we never talk)
However I'm jut thinking there probably needs to be more actions than words so I'm gonna start reading stuff in the SSM forum for some inspiration.
