My first wife and I were very uneducated about sex when we got married. We were also very conservative... almost thinking that the only reason for sex was procreation.
Our honeymoon was the first intercourse for either of us. Neither of us were prepared for the amount of pain and bleeding she had. She would not have sex again for 2 months and then only reluctantly out of fear of being hurt again. Sexual differences between us grew as I kept learning about it but she staid stuck where she was. Eventually, we got a divorce.
