ED not a friend while TTC...

My husband has never ever had ED, always able to do it and finish. Now with the pressure of TTC he is having problems. I tell him it's all in his head but it doesn't matter... Now he's at the point where he doesn't even want to do it because he's embarrassed. I'm avoiding putting any pressure on him but I don't know what to do... Any advice? We both really want a baby, him even more than me but it's not going to happen when we can't have sex!!!!😫
