Erectile Dysfunction

Hello everyone. I am TTC and when I tell my husband it’s go time (I’m fertile) he has difficulty maintaining or even getting an erection. This has happened every time we have tried to conceive all 3 times. Has this happened to anyone else? I’m desperate to do anything I can to help him! I’ve gone down on him until my mouth hurts, and done anything in bed he’s asked me too, and as soon as I tried to get on top of him he loses it. Anyone have any advice or insight on how to help him chill out?
