How do I get my husband to stop going ‘Goblin Mode’ during sex?

My husband says ‘Goblin Mode activated’ when we start to have sex, growls and acts like a caveman, and then says ‘Goblin Mode off’ when we stop, and then pretends not to remember afterward
.
I really love my husband and he’s always been great in bed. But recently he’s been acting really weird. I’ve heard him muttering, ‘Goblin’ repeatedly when he didn’t notice me, staring blankly into his food, and just going alone by himself to do who knows what. I feel awful for him, but we both agreed that this was for the best. Last night, the day after our son went away, we decided to have sex to relieve our stress. However, my husband said ‘Goblin Mode activated’, starting growling, and went wild having sex with me. Admittedly, it was some of the best and most experimental sex I’ve ever had, but I’m worried that something might be going on with my husband. Any advice?

+rep good mate.
