the Church was put here on Earth to show us what is pleasing to God and waht is not… There are some sexual acts that are NOT… and we need to know aabout that because sometimes people can’t figure this stuff out on their own…
that is not saying they are stupid… and if it is saying that… I’m admitting i am not so bright sometimes…
for instance… one could say that test tube babies is a good thing (pleases God?) becaue life is brought into the world and "good " people who couldn’t otherwise have children now can…
yet, the Church studies this kind of thing, knows the details… and is in the position to tell us that this is NOT t he way God wants procreation done…
not all people think like the Church… until they hear the Church’s position… (and even then…

)…
it is the same with other sexual activities…
