Sex advise??

I am trying to spice it up a little, my sex life is very very little. Sometimes we only ever have sex during my fertile window, I’m trying to just kind of forget about trying right now and focus on us and have more fun sex and not sex cause we want a baby. What did you guys do in this type of situation to spice it up and have more sex??? TY!!!!! ❤️❤️❤️❤️🥰🥰🥰🥰
