I don't think not having sex outside of marriage is all about self-control. Your statement assumes that it is outright wrong to have sex before you're married, when in reality there is nothing wrong with it other than the false construct that some people of the world have chosen to follow. So assuming that it is perfectly natural to desire sex from the time that you are sexually mature (way before most people get married), which most likely relates back to our natural instincts of both pleasure and survival, why should you admonish someone for simply acting on it? A catholic telling the world that they must wait for marriage before having sex is just as ridiculous as someone of the islam faith telling the world that they can't drink alcohol. Both are personal beliefs that are nothing more than constructs of the faith that they chose. If everyone in the world followed both of those rules strictly, a lot of problems would disappear... but that is unreasonable to ask, and arguably unjustifiable. So the question becomes, if people are going to have sex, how can we minimize the problems associated with this perfectly natural and desirous act? One of the cheapest solutions is condoms, which the church has publicly come out against... and as a result, they've had a directly negative impact on the STD transfer rate in Africa (and the world in general).
