THE POINT OF SEX IS PLEASURE. everyone knows that, and you do too. dont play dumb. the fact that it gets you pregnant is an afterthought.
and finally, money isn't just "lost" when it's spent. where did the damn money go? to the void? it just changed hands. the problem of "lost money" only occurs when there is an inefficiency which is keeping a given market from reaching its full potential. guess what, the church creates a lot of these inefficiencies. when people want and then have a child, they know they are making an investment that may or may not benefit them directly, but they almost certainly hope the child will live a fruitful life (i.e. will provide goods and services). the money in that situation is not just "lost." however if having a child you didn't want prevents you from finishing school or working at your job, then money was lost due to that ineffeciency (you believing in the church).
First of all, sex is not just for pleasure, at least to the Christians. IMO, that was a very ignorant and biased comment that you made. Unlike you, people actually preserve that special moment for life; not just having sex all around with whoever you want to. Not everyone's horny.
Secondly, you wouldn't have to worry about your financial problems if you're a Christian. Sure, families want to help their child and support them, but what family doesn't? How exactly does being a Christian mess your money up? At mass, people choose to give money, it's not mandatory, unlike some religions. And me "believing" in church? Not necessarily. Some of the church's teachings I do not agree with, mainly because those teachings are usually contradicted by the Bible. How exactly do I lose money by going to church? Do I pay for confession or the Eucharist? Do I pay to go to mass? Do I pay the priest to administer the Body of Christ? No. Most, if not all church functions are free. They don't force this religion on me. If I didn't want this religion, I would become an atheist, but that's not happening anytime soon.
