Well sex before marriage is something that has been hanging fire among youth ever since, just that discussing it is more open now.
Definately I agree to the fact that we are nonetheless animals who have sexual cravings like any raw animal. Before or after marriage question is decided on a simple fact; your comfort level in being exposed to 'N' number of people. And by exposed I do not only mean physically, but beyond that. So its all depending on person to person.
Thats how i take it. For the record... I stand for sex after marriage
