How to have more sex?

My hubby and I are going through a rough sex patch. I am so exhausted I just can’t bring myself to do it, and I completely take ownership of this and I know it’s not right. My husband doesn’t even try anymore because ive always said I’m too tired. We only do it like 2 or 3 times a month now which neither of us want. My hubby said ideally he would like it every other day and I would like t more too. I’m a nurse and after 13 hour shifts I’m dying and fall asleep immediately after getting home. We eat dinner and plan to have sex but then I fall asleep on the couch. Also I’m an early to bed and my husband stays up all night, I’m afraid he’s a porn fanatic because of our lack of sex. What strategies do you use? Surely those with kids have more sex than me so they must figure out a way. I tried initiating in the morning but I find we both sleep in until the last possible second before we absolutely need to get up. I really want to make this a priority and I dont want to let it slip. I’d love some suggestions ❤️
