My husband told me he had no interest in sex either, until I found out he was addicted to porn and viewing it on the sly, then masturbating so much he had nothing left for me, which made me feel rejected and used when we finally did have sex. It became a vicious cycle. He distanced himself from me because he was thinking about his next "porn session" so I rejected him and noticed everything little annoying thing he did which turned me OFF which made me NOT want to have sex with him at all! When I finally confronted him with it and told him I would NOT tolerate the porn, he said he would stop, but I can't help wondering if he is now resenting me because I've blocked the porn sites with "parental controls" on our computers. I hope your husband gets the help he needs and you can resume to a happy, mutually satisfying sex life.
