TTC and hubby having trouble finishing

Does anyone else have this problem ?? I'm sitting here upset now bc i feel like it's me even though it's probably not... I am using the ovulation sticks to find out my fertile window so as soon as I got the blinky face for high fertility, I made hubby have sex with me. So that was 3 days in a row. Today I got the static smiley face which means peak fertility so of course we need to have sex today and tomorrow but we just did for like 45 mins and nothing. Had to do it twice yesterday too bc he couldn't finish the first time. I'm like dude u have one job!! Just cum! Don't even wait for me ! (He usually always does). I know I know I'm putting too much pressure on him and I should just chill out and let it happen naturally. Just want it to happen soon bc I am 33 and we are ready. And he's like oh it's bc I'm tired and sore from yesterday blah blah blah and I'm like dude I'm sore too but suck it up lol. Anyway after typing this I definitely know I need to chill out but like ugh I just think of all the other times we had sex for fun over the years and he accidentally finished. And now when I need him to he can't lol.
