Not attracted?

Just within the last few months my SO  decided to try and have a baby. We have been together for over 6 years and normally have sex maybe 5 times a month.. Now since we are trying my sex drive is way up there but now it seems like it's always a chore to him and I alway initiate and foreplay is non existent... What can I do to make it fun and get him to want to have sex and maybe he initiate.. I am tired of him being "ok get it up" and wham bam thank you ma'am 😕
