It took me a long time to learn this, but it usually works if you just slow down. Take time to let her talk about her day, tell you how she's doing. Listen well and show her you care about her more than just physically. Demonstrate your love by buying her something that SHE likes, even if it does nothing for you, such as a nice cozy robe and slippers. Change the sheets on the bed before she gets home--new sheets are even better! Light some candles. Make dinner, even if you're a lousy cook. She'll appreciate that she doesn't have to do it. Tell her to go relax in the tub, then straighten the house (some women can't relax in bed if the house is a mess--my wife is that way!) Turn off the TV in the bedroom. Read an erotic (but maybe not pornographic) book together in bed. Have fun.
Good luck!
