another thing...maybe try having sex in different places.....maybe the bed is way to comfortable for you .....perhaps having sex on the floor....on a table....hey ...ill tell you what...ive had to do it in the bathroom with my bf...because we never have privacy anymore...gaurntee you wont fall asleep there...lol

i would also agree with going to see a doctor....
but i did listen to a sleep specialist on tv....and he said why most people cant sleep when they go to bed is because they do other activities in bed...like sex....and tv....and reading....he said to make sure you are able to go to sleep in bed right away....is do things elsewhere...if you have done this...not had activties in bed...your body is soley used to the fact that you go in bed to sleep...not have sex or read or even watch tv....you probably have one of the best sleep scheduales a sleep specialist could see....if you dont apply to this than yea...go see a doctor...well even if you dont apply to this go see a doctor ...good luck
