Well, this answer is different depending on the people involved. The act of sex, and the act of making love are two different things. Many people may disagree with me, but trust me, if you determine whether you are interested in having sex or making love, this will make a difference. Sex may occur the second you meet... or shortly thereafter, as there aren't REAL, AUTHENTIC feelings of love involved. Making love, should come at a point in which you have determined the strength of love for this person. Say this was going to be the girl you were going to marry, you need to be sure that the feelings you SHOULD be putting in to making love, are feelings you can continue to put in to making love for the life of your relationship. Think about it, you wouldn't be too happy if your gf/wife wasn't putting her whole heart and all her energy into making love, the closest that two people can physically ever be, in which both of your hearts race, and you enter a state of ecstasy, far surpassing any other form of enjoyment you can achieve in life... so know that she wouldn't be happy if you weren't putting all of your heart and feelings in to it as well. So you need to make sure that you are at that point, and even consider asking if she is ready to put her all in to this as well. It should be special, as this is an activity that only you two should be engaging in, and that makes it unique. Once you are sure you are at that point, then you get the green light. Good luck!
