He is failing in benevolence (kindness) which comes before the sex in the Biblical teaching of 1 Cor 7. If you feel dirty, he should not be demanding it period. That is extremely unkind of him.
I learned in counseling that the demand for certain forms of sex (BJ is one of them) is a common characteristic of men who view inappropriate content and is not about love and intimacy but control.
When I was delivered from flashbacks to childhood sexual abuse, I drew the line in the sand and stopped doing certain acts which made me feel dirty and I have never looked back. My deliverance came instantly upon the realization that what happened to me in childhood was abuse. My husband's deliverance from inappropriate contentographic images and sexual addiction was a process. There was a spiritual stronghold involved.
Like visionary, I had supernatural experiences. For example, I prayed that I would be able to be the chaste wife spoken of by Peter in 1 Peter 3 and by Paul in Titus 2 . Sometimes, I could feel the lust coming off of him and I prayed that he would NOT be able to come at me with lust. For awhile it was like the Lord put a bubble around me. Whenever my husband came near me he was impotent. He could still jerk off to inappropriate content, but he was impotent with me.
The experience made me feel incredibly loved, cherished, and protected by God! It scared him because he used to preach with such zeal: "When your ____ causes you to sin, cut if off!". His ____ was causing him to sin and he was terribly afraid God had cut it off.
