TMI help

Ok so DH and I have been married almost 11 years..we have been trying for 9 years unsuccessful except for 1 miscarriage back in '06. A few years ago DH began having issues with keeping his erection during sex. This made it, as you can imagine, stressful for both of us. He refused to get help, like most males not wanting to admit that there might be a problem down there. Finally a few months ago he went and got some medicine, which is stupid expensive because insurance doesn't cover it. The sex is better even when he doesn't take the medicine. The problem I have is getting in the mood when for so long I felt rejected. (He wouldn't finish and left us both frustrated) I honestly have no idea how to get over it...I have tried. We do have sex around ovulation but that is about it. Any advice...(I also have PCOS).
