I nteresting Matilda, my H has the same problem sexually as your H since his affair. I thought it was because of prostate problems, but maybe it is more complicated than that. He never had a problem with performance before he slept with her. He tells me he had the same problem with her, but I don't believe him. Is it guilt, or am I the problem? He has had every test for STDs imaginable. It was his idea to do so which makes me feel better! There are days when I am down too, especially because he is so far away and very busy with work.I wish he was home but he won't be for three more weeks.
