You didn't mention this but have you just tried talking to him about your frustration? I mean literally tell him that you are getting frustrated. Tell him that you have needs to and that he needs to help you understand why the sudden disinterest. Ask him direct questions, whatever you want to know. I have always been a very open and honest person so I would ask, "don't you want me anymore? don't you love me? are you interested in someone else? don't you want to please me? See how he answers. Maybe he is depressed. Is there anything different going on in his life, your lives? Is he always with you or could he have interest in someone else? I would not let him "get on and off" anymore, I would say that you want foreplay and then ease into that. Set a date night at home, candles, wine, appetizers for dinner, get a movie, etc and then at bedtime have a little lingerie on and start slow. Tell him to relax and let you take over.....set the mood for him. DONT let him on top of you though until you have had yours. ;o) I hope it works out for you, I would be so upset too! It is about give and take, not selfishness or you don't get yours either! ha ha Have you tried 'movies'? role playing? Make a game out of it, act like you are someone else and walk into the room with him and start your role, he will not get it at first but keep it up, he will eventually get it. something like, "excuse me sir, is this seat taken?" then go on from there.....Or throw him down on the bed and proceed to pretend like he is at a bar....you get what I'm sayin'. :o) If these do not work, he needs help. Truly, he could be depressed, stressed, etc
