Kyleena IUD no condoms

How many of you guys use condoms with your iud? I’ve had my kyleena iud for about a year and a half and my boyfriend and I always use condoms but we didn’t last night. He didn’t cum inside of me but still wondering if I should be worried about it. I know with iud it’s like 99.8% so i guess that’s why I’m asking how many of you go without condoms?
