It depends on the day, what we have planned for the evening and how I am feeling.
Sometimes we go to bed very early (8 or 8:30) so we will have time for a lot of sex. Sometimes, we go to bed at 9, for the same reason. We do have sex when we go to bed later, but my husband wakes up at around 4:20 in the morning, so when we stay up late on a weekday, he has a hard time getting up. Yesterday morning, he slept until 6:20! I realized we had overslept, but he had been out of town on a long road trip (more than 1,000 miles driving one way and then 1,000 miles the next to take our oldest daughter and her partner to their new home) and was exhausted.
