sounds like home life consists of him going to work, then coming home and still having work or whatever else is going on still on his mind. once you get away he is able to release all of that stuff and relax. sex at home is sometimes awkward at my house too. it usually takes something that turns both of us on to get things going like a movie or some dirty talk. I am a guy and I have noticed that when we travel or even when I travel alone I get hornier for some reason. maybe you two could just take mini vacations and go somewhere not too far away. it's better than nothing! also, as the previous poster said, keep plenty of batteries ;)
