“I really would love to have sex every morning before work as well, and my boyfriend is very aware of this. However, he values sleep so much that he wants to sleep until the last possible moment that he needs to get up for work.”
If you both want opposite things, there’s no way for either one of you to be 100% happy with the outcome. You both have to give a little. It sounds like you’ve been pushing for sex every single morning- in other words, you’re telling him that you want things to go completely your way. You’re trying to persuade him to action, because all he has to do to get his way is just stay asleep. If want to persuade him, you have to think about what he wants and reach a compromise.
You may be coming across as aggressive or insensitive to his needs, as in, “He already goes to bed sufficiently early on weeknights (usually 11pm), and I definitely would not want him to go to bed any earlier because I require less sleep and am usually still awake when he goes to bed anyway.” If he sleeps in until the very last second, he’s probably still tired when he gets up. Maybe he wishes he could go to bed earlier or sleep in later. Some people just have lower energy levels than others. I’m one of those people who sleeps in until the very last second. On a work night, I think seven or eight hours of sleep is ok, but getting up on that amount of sleep is really a drag. I would get nine or ten hours if I really could.
Try to think of alternatives that allow him to get as much sleep as he needs and you to get more sex. You might need to let him go to bed earlier after all in order to get what you want. Or you could surprise him by helping out with some of his morning routine, like making breakfast or coffee or laying out his outfit the night before. Then he’ll have some extra time in the morning that you can spend together. Maybe you can schedule a morning in or a sick day together every once in a while. He still probably won’t be willing to wake up early for sex every morning, but that’s why it’s a compromise.
