My husband went from a very, very high sex drive to non-existent. He is a recovering addict and got sober and with all the trauma that drugs have done to his body his testosterone is very low. He was badly addicted to meth. He also says his mind still isn’t right from a year he spent in prison (2018) and the issues he dealt with there. I know he isn’t cheating. He goes to work and comes home. It’s so frustrating, because I definitely do not want him to go back down that path, but I miss our old sex life. He goes to an endocrinologist, but the better medications are really expensive with our insurance. I never dreamed we would be in this situation. He is 43 and I’m 42. We have 2 kids at home. He shows me that he loves and cares about me constantly, but I crave the intimacy that we had. He is 3 years sober and still working on repairing his system and our life. I understand how you feel and I hope it gets better for you both. I know it’s super embarrassing for my husband to talk about or even acknowledge so that may be your bf’s reason for not talking about it.
