Performance Anxiety

I’ve been with my partner for over 9 years. We are both in our mid 20’s and have explored new things together intimately (anal sex, toys) throughout our relationship. As we’ve gotten older we began to have sex once a week which I’ve been okay with. Even though I have a higher sex drive, I accepted that this is how things are going to be.

Recently we hit a rough patch over the last month. We only had sex in the middle of night when I’m sleeping, still once a week. He hasn’t tried to be intimate with me when I’m awake. I even tried to initiate sex but was turned down. I talked to him about it and he shared with me that he feels like he needs to prepare for it and worries about how he’ll perform.

Has anyone in a long term relationship experience this?
