Sex advice!!

Ok ladies.... my husband and I have an ok sex life. When we have sex it's amazing... we just don't do it that often. He has a terrible sex drive, so sex 3 times a week is a GREAT week for him. But too often we will have sex 1 or 2 times a week. Now I've tried so many things and when I do them they work 8 times out 10. He has the most trouble when it's my fertile week... it's like I have the cooties...lol. I have told him how I feel and he's well aware. So he has been trying every libido supplement he feels comfortable with. He feels like he's letting me down in my fertile week, he says he gets in his own way because he thinks about it too hard and he get stay erect. It's like performance anxiety. So do any of you ladies know what WE can do to help?
