The truth sill remains that you'll be forsake if your people find out that you are having sex before marriage, especially the Church members. They consider behaviors like that very adulterous, but come to think of it, why should I care? Sex before marriage is completely up to the couples. What if you do not engage in developing this segxwal feelings and it end up being disastrous on the honeymoon night? As for me, I would say there is absolutely nothing wrong with it. So long as you are honest about how you feel about your partner, and you are not doing it to get to his or heart. You should have each others heart before indulging in sex even if you do not plan on getting married because their maybe circumstances that will reveal to you that this marriage was not meant to be. You cannot force nature.
