My wife flat out said: "Don't wait for me to initiate sex". She wants frequent sex, but wants me to initiate all the time. I like the arrangement. It would be totally pointless for me to wait until she initiates. We both know by 6PM if it's happening tonight. If it happened last night it's not even a topic. There's an understanding that I wait 48 hours before initiating again. The exception would be Saturday mornings. If we get busy on Saturday morning, Sunday night is a possibility. Another exception is vacations. Daily sex is normal on vacations. She likes it when I'm showing interest in sex even when she says that she wants to wait until tomorrow night.
