Let us be clear on this one:
Subtle hints do not work!
Strong hints do not work!
Obvious hints do not work!
Just say it!
this cant be more true, it's like women saying "come to bed honey" translation: i'm horny,lets have sex.
being a man the answer is "well i'm not tired" if not, and continue watching "Mail Call" on the history channel or the "barrett-jackson auto auction" on speed. then when you do get to bed, it's cold as alaska in the room cause she's upset.
or if tired, get in the bed and go to sleep.
then the next morning when trying to get some before work sex she's like, "i was ready last night"... dresses and mopes around the room.
and men are like

why didnt you say so ??!
come on ladies!! what do us men do when we are horny?? you turn your back, turn back around again and WHOOSH, there's a dick in your face! we dont do hints!
