TTC anxiety

I have endometriosis. I had my second surgery in may, and also saw a fertility specialist. I had my full workout and now it’s my husbands turn to get sperm analysis. I feel like ever since I’ve had my work up, he’s totally in his head! He almost never can get in the mood for sex when it’s time, and he hasn’t gone for his analysis yet either. It’s been MONTHS! I feel like we have less sex now, TTC, than ever. I think he’s in his head and worries about it being “his fault” we aren’t getting pregnant. I don’t know what to do. I put him on fertileaid 2 months ago to help sperm quality, but it hasn’t helped libido. Any suggestions for boosting libido?

Fertility doc said to just get viagra, which we did, but he hasn’t taken it yet! 😩🤦🏼‍♀️ help.
