Absolutely zero interest in anything

ok, so I am a cis gender male 26, married for 5 years to a cis gender female 23. When we first got together the first few months we had sex a lot. 8 times a day on a few occasions. Well we now are to once maybe twice a year. I have lost all interest in any sexual act. I fake orgasms just to stop it. My wife is getting to the point of wanting a divorce due to it. I'm currently taking Viagra hoping it will help. I can't even masturbate. Everytime she initiate I naturally just redirect. Help me figure out why I'm so much if a screw up.sge gets pissed calling me weird for not even eating her out, I've never been into it and I find it repulsive and always have. I feel like a broken man.
