My best friend from childhood married a man after 2 years of dating and they were both virgins.
After 5 years of marriage, his porn addiction was brought to light when he got fired from the church he worked at--- because he was jacking off to porn in the church office.
They went through therapy and she researched so much about porn and how porn addiction escalates into other perversions.
Their sex life got painful and demeaning to her. She was thinking of leaving (this is 10 years in).
She left last year when he admitted to molesting their 2 year old daughter. Twice.

She called the cops and he is on probation as a sex offender. For life. Good. Ass.
She wishes to god she knew about his addiction and perversions before marriage. After all this came out, he told her about his past (before her) and what he was into. It was sickening. She wished she never married him. Now she's a single mom of 4...one child has severe autism.
What I'm saying is, you KNOW he is like this and you aren't married.
DO NO MARRY HIM.
Be thankful you have seen the light.
