That's the wrong question to ask under these circumstances, since nobody else is imposing their beliefs on you and preventing you from practicing those. The real question is, must sex invariably lead to pregnancy when there are known ways to prevent it? Because that's precisely what you're trying to impose on others. Your answer is clear from your comment. But it's completely illogical. Nothing in the laws of nature say that humans or any other creature can't use their creativity to disrupt the natural order of things to make life more comfortable. To my knowledge, no other creature uses fire to cook food. Yet, human digestive system is uniquely adapted to that. And other animals don't cultivate food on the scale that humans do. Many of the food crop species won't even survive without human effort. I also don't see many other animals using clothes or money. So are you ready to give up those unnatural things - cultivated and cooked food, clothes, money and all modern technology? The same goes for vaccine - the natural way of diseases is for children/people to simply die on a massive scale. What's the point of going through that when we have a way of preventing it? Why must it be any different for contraception and treatment of STDs? The real issue here is the imposition of certain beliefs and moral values that are stale by a few millennia on an unwilling population.
