Or it refocuses his anger toward "The Ho" that destroyed his trust and he becomes permanently distrusting of any woman willing to have sex with him as another potential "Ho" who has no loyalty and only has sex with whomever she pleases.
He needs to first get past this and then rebuild his trust of another potential mate slowly and thoughtfully. This isn't about sex. It's about betrayal and trust that has been seriously damaged. The only way to heal is to accept what has happened and find a way to trust again...if he is ever to have a chance at a normal relationship again.
