My husband is having issues performing...

My husband hasn't been able to stay hard during sex lately. My husband's mom told him about her getting drunk and telling me about him being sold into sex trafficking by his friend. The only reason I didn't tell him she told me is because I agreed with what a lot of you said about him being the one to come to me and it's his story to tell. He said he wasn't upset that I didn't tell him and the reason he didn't tell me is because he didn't want to appear broken and he didn't want to be like men who use women has rehab for their trauma. But every since she told him that he hasn't been able to perform. He has been trying and he either can't get hard or stay hard. He's too embarrassed to talk to his therapist about our sex life. I've been patient with him and we've just been intimate and other ways. Lately he's just been going down on me to at least get me off. Is there anyway I can help his mind get back in the right mind set for sex?
