Years don't matter when we talk about love but they do when sex is in the question. Losing virginity before 18 wouldn't be so good. Simply, you lose it when you need to lose it and you need it when you feel it. Sex is what we need to achieve biological life point, but sex without love is like a bird without wings, nothing than satisfaction that comes from mind instead of coming from the heart where love actually must be. If it is not in the heart then it is not love, its only good feeling when you are together with somebody.
