I finally ovulated and my husband can't preform...

We have been trying for 8 months. Last month, I went to the dr because my cycles were getting further and further apart. She said oh I just think it's irregular cycles, but I'll do some blood work to make you feel better. (Her exact words were "to give you peace of mind")
Well, the results came in and I have PCOS. Okay, cool. I was upset that I had it but glad that I had an answer as to why we weren't getting pregnant. 
Scheduled an appointment to discuss fertility medicines, and she put me in clomid. Luckily, I started my cycle an hour before my appointment so I was able to start it 4 days later. 
Well, we had intercourse Sunday then tried on Tuesday night, Wednesday morning, and Wednesday night. Annnnd he can't get it up. :( I'm devestated but don't want him to know. 
I don't know what to do though, I don't know what to say. 🙁
