Performance Anxiety

Since we decided to start TTC, my husband has now and then had performance anxiety issues. Because of opposing work schedules, we have agreed to try to BD every other day during my fertile window. Last month, he couldn't go through with it citing performance anxiety - it was disappointing and upsetting for both of us. I know this isn't uncommon and I'm confident that there is no underlying doubt ... I've decided to not mention anything next month and just jump him. Thoughts? Anyone else experience this?
