I have found that it is important to keep things fun in the bedroom. A good male friend gave me advice when my husband was cheating. He told me to buy the sexiest lingerie I could find and to do everything I knew how to turn my husband on. I figured a man must know, so the battle of the bedroom began. I bought a very sexy black bra and "naughty" panties from Frederick's of Hollywood, with the thigh high black fishnet stockings and high heels. And while H was taking a bath, I put it on in my closet, and came out looking like an over-the-hill playboy bunny. He looked shocked for a moment. But he got out of the tub pretty quickly and we had very hot sex that night.
I now have a collection of little nothings from Frederick's and I will never wear them out, because they are never on for more than a few minutes! On his birthday I bought the bellydancer costume and, since I take bellydance class, I practiced a number and did a little bellydance for him. Tonight's Valentine's Day, so I guess I'll wear the red outfit.
This has really been a wonderful, fun thing for two old married people. If this is what they mean by "marriage takes work", I don't mind.
