I think dating is the process to get to know one another. If you sleep before it still doesn’t guarantee it will work. You don’t want to have extra baggage. Not saying it won’t work but marriage is better. It’s not like marriage will work either but do things God’s way and have faith it should work out very well
Do things God’s way, and the obedience that keeps you near Him will give you life, whereas the stubbornness in which you would have had to defy Him will leave you to your own unhappy judgment.
More to the point in a secular setting: You have the authority to decide that “as for me and my house, we will serve the LORD.” (Jos. 24:15) That is reason enough.
There are even Catholics out there who will try to sway someone they are dating with arguments that imply that the right to bodily integrity is not absolute, that a person has to have some argument that convinces their dating partner before they have a right to withhold sex. Nothing could be further from the truth. When you marry, you promise that you will give your body to your spouse. Otherwise, no one has a right to expect you to have to come up with some reason to refuse to have sex with them. They do not have the right to conclude that you do not love them, that you are selfish, that you have a warped view of sex, or any of the rest.
All those arguments are a big con, and a con that
most adults, religious or not, knew was a con not even a hundred years ago! All this business about “harming ourselves by repressing our biological function of sex” and “having sex is what people do when they truly love each other” and that it is “selfish” (!!??!!) to even hope your spouse will not have fallen into sexual sin before you marry each other and whatnot is nothing else but an excuse for pressuring someone who has unassailable principled reasons for refusal to engage in extramarital sex to give in and agree to it, anyway.
There is NEVER a necessity to engage in extramarital sex. Anyone who tells you otherwise is lying to you. They may be lying to themselves, too, I do not mean that they are consciously running a con on you. Their thinking is mired in a lie, though. They are certainly either deceived, deceiving or both. Do not let yourself be made to feel like a “prude” because you are not drawn into this lie with them.
Even in a totally secular setting, there is an increasing awareness that this right to bodily integrity is real and supersedes all the “biological urges” and other arguments in the world. Stick up for it, always, even among non-believers. The secular world needs for people to take that right back for themselves–that is, the right to say, “no, we are
not married and I do not
need to give any reason to refuse to have sex with you”–very desperately. Even a prostitute has the right to refuse to have sex, and owes no one any excuse. Every person who has not promised their bodies in marriage has that right. (The person who has promised his or her body in marriage can still legitimately refuse to engage in marital relations on occasion, but does owe his or her spouse a reason for refusal.)
