From the how far is too far files: I hear young people ask the "how far is too far" question a lot yet I never hear any adults given them a straight shooting answer. Here is what I wrote about it on DCF
OK, I am going to sound like a total prude here, but I think this is something that should wait for a very long time, like the wedding. The physical aspect of marraige is the ICING on the cake. I know the temptation to lick the bowl, or swash your finger in the icing is pretty high, but lets get things straight, we all know that waiting to eat the completed cake is preferable to any alternative.I wrote this over a year ago and after hacking and various other things should have caused it to fall away into the abyss of old forum posts, there it was preserved in its original state. It caused a mild stir ... it is pretty radical after all. Now you have read it too and I still stand by it.
Besides, I think we are treading on thin ground here, as we all know that kissing leads to other things and there is little doubt that it gets you physically aroused. My understnading of 'openness' to life is that once the process has begun, we should give ourselves totally to our spouse. That isn't fully possible until you are married. Don't even take the risk at being in a compromising situation where the area is gray. Besides, you certainly shouldn't be considering how well someone kisses as a factor in choosing a spouse. .
All of it can wait and in my opinon, that is the optimal way to do it. Give yourself TOTALLY to your spouse and only your spouse.
