Sex is first and foremost the biological act of making babies.
Damn right its fun and feels good...nature wired it that way to make sure we did it to give the species the best chance at survival.
Of course, this opens up the "can of worms" that this is somehow a "religious right" view..regardless of the simple truth that this is the purpose of the act. (period).
What we now see is a push to "it feels good so do it" and we've spent alot of our higher brain function on that aspect. How do I keep doing it WITHOUT the biological outcome. Hey, no problem.
BUT, this attitude has created some fundamental issues in society between "factions".
Whatever your faction is, denying that makin whoopie has the side effect of makin babies is denying nature. There's also the fact that it also has the side effect of sharing some fairly bad bugs. Reminding folks of these things shouldn't be an issue.
And there is, regardless of your religious persuasion, only one way to guarantee none of the bad comes to pass. Thats not to do it at all. The real issue is why we need the government to tell us this. And the sad truth is because we don't have a solid enough family foundation left for most.
I agree with you in that there are many woman making the choice to have babies without being married. Sadly, though, they are likely the vast minority...and what we are doing is guaranteeing a continuous source of an underclass by not attacking the problem in some fashion.
Current governments way isn't necessarily the best way...but giving everybody a good dose of hormones and saying "have at you" isn't necessarily the best way either.
