My husband started experiencing these problems years ago. I actually believe that was the beginning of his MLC. He would have problems keeping an erection, then would feel awful about himself. I realize men feel like their bodies have betrayed them, and no matter how loving and understanding I was did not change a thing.
That's when my husband started pulling away/distancing himself from me. He told me once that he did that because he was afraid cuddling would lead somewhere he couldn't take me. So, it was easier for him to not put himself in that position in the first place. When I complained that he was robbing me of love and tenderness, he said he didn't think he had any choice.
One time when he did manage to keep his erection, I mentioned to him that I thought the problem was all in his head.....the one on top of his shoulders. I remarked to him that he had been in a better mood. I saw a correlation between his negative thoughts about himself and his ability to perform.
I can only speak from my perspective from my own marriage, but it seems to be part of the larger pattern of negativity. When someone in MLC starts to doubt themselves, starts the negative thinking, or what I call "stinking thinking", which leads to vocally spewing, they seem to dive headlong into depression. When they keep going over these negative thoughts about themselves over and over again like a broken record....they actually believe all these lies are true! So, therefore, the husband who feels like he is a failure at everything in life, certainly also believes he is a failure as a man. Hence, the impotence. He convinced himself he can no longer perform and now is worthless in our eyes. Which is total crap from what we actually think of our husbands!
My husband tried Viagra, but had such horrible side effects that I just couldn't put him through that anymore. He told me his eyes burned and he thought they were going to pop out of his head. And it gave him severe migraines. Not exactly the best state of mind for making love.
I even tried to assure him we would learn to deal with this, but he would have none of it. The distancing began in our bedroom and then ventured on to every room in the house until he walked out the door. He became very irritable, angry, and sometimes cruel with his words. I begged him to go to the doctor and he finally did. However, he lied to me about what the doctor said.
After he left, I found out he told the doctor we were having marital problems and that I was the problem. Of course!!
I confess that since that time I have badgered myself at times wondering if there was something I could have done differently to help him. That perhaps if I had said, or acted differently, or paid more attention that this was the beginning of depression and could have forced him to see a doctor, we could have alleviated all of this. You know, it's the old coulda, woulda, shoulda!!
Well, the truth is, everything that happened was because my husband chose to believe the negativity and acted accordingly. I could not have changed anything. I have educated myself on MLC, male depression, impotence, etc. and nothing I have learned would have enabled me to change my husband's mind. God gave him free will. The only thing I can do is to continue to pray for him.
I don't know if this helps you in any way. It's just what I've experienced so far. I think they become their own worst enemies by being so critical of themselves. I know that when my husband was in MONSTER (which he seems to jump in and out of frequently!) and was spewing, some of the things he said about me, I knew he was really talking about himself.
