My poor husband!!

So I thought we were past this issue of erectile disfunction but apparently not. My poor husband could not get an erection tonight for our Christmas sex. He’s been dying to have sex because it’s Christmas and it’s tradition but my poor husband just could not get it up and keep it up. Just when we get it up he loses it after 5 minuets. Poor guy is just sitting on the bed pouting now. I feel so bad for him! Any advise ladies. He had viagra but hates taking it cause he gets super flushed and his heart races and it doesn’t really work all that well.
