This is the first time my husband strayed after 34 years of marriage and had 2 sexual encounters with his much younger affair partner but my husband insist that he can’t perform no matter how both tried and that ended him very embarrassed. He asked the affair partner to meet for the second encounter because he thinks he can better perform after he took a vitamin pill but unable to perform again. He ended the affair after those encounters. Is he telling the truth or gaslighting me?
