Does anyone know if a man is embarred if he had a errection problem?

This is for the guys. I had a date with a guy I've known for 2 years. I decieded we could have sex. He inishiated the sex part. He had been drinking a few beers earlier that night. The problem is he couldnt really get it up. He said he didnt know what was wrong with him and that next time it would be better. This happend Friday and now he is ignoring me. We work together. I am in the office and he is out in the field. I spoke to him on Monday very briefly. He said he would call me back and hasent yet. I dont know what to do. I'm not sure if he is embarresd or what. Please help.
