I don't think there is such a thing, brother. God made men and women, and he made them to desire one another. Those desires are something to guard against as an unmarried person, especially when you're getting close with a special person in your life. Even if there is a way to totally avoid sexual desires during your dating phase (ELIMINATING it is impossible), there are no pat answers that someone can give to work in every case.
Everyone is going to have problems with different things, and it is important that you communicate those problems with your beloved. Maybe you need to watch how much time you spend alone, limit the amount and type of touching and loving expressions, dress slightly differently, etc. Rules and boundaries are a good thing, as long as they don't become Pharisaical. Remember that the key point to all this is to glorify God by doing what He wants...you don't somehow get brownie points for saving your first kiss until marriage. It may be a tool you use to keep God as your focus, but to think of it as more than that is treading on dangerous ground.
