My boyfriend and I have been together for about 3 years, and when we started the relationship I told him I wanted to wait until I was married to have sex, he said he was fine with that. But we put ourselves in the position where we were tempted and gave in to that. We now have a 16-month-old son. I told him that I am sticking to my guns this time and want to wait until I am married. He feels that I can’t make that decision for him and should still give in to him. He says that we have already done it and it doesn’t matter. Could you give me some scripture to back up my decision, also suggest some things that he could read to gain an understanding that just because you sin once doesn’t mean you get to go on sinning.

Read carefully what Paul says in 1 Cor. 7. His advice is that one should get married if one wishes to avoid immoral sexual activities. Your boyfriend is letting his hormones do the talking, and yes it does matter to God. Sex is a gift from God. Indeed, sex is such a great and beautiful gift from God it should be reserved for the person one is prepared to give one’s life and love to unconditionally in holy matrimony.
