How to not add stress in sex trying to get pregnant

We’ve been trying to conceive for about 6 months now. I have a higher sex drive than my husband which is fine, but obviously in your fertile window you need to have sex many times to increase chance of pregnancy. I feel like he is already annoyed and feels pressured. I don’t want it to feel pressured or add stress but It’s hard when you have a small window and literally need to do it multiple times. I feel like I’m the only person who needs to “make” their husband have sex with them instead of vice versa 😂
