I'm in a relationship where both of us are born again Christians.  In the past, we've been sexual and have struggled with lusting so bad. Honestly, I feel guilty about this, but not really guilty enough to stop. However, my boyfriend has went through the motions of feeling so guilty. About a month ago, he told me he wanted to stop having premarital sex or doing anything sexual to bring our relationship close to God. I was fine with that, even though it made me a little upset I accepted it. A few days ago, however, we messed up and sexted and even planned to have sex when we saw each other again. Now today, he told me he still feels that it's too wrong and he feels too bad after he does it. I respect this and him but it's so hard. Does anyone have any thoughts or advice?
