Sex is a huge part of life and something that should be celebrated as a free act rather than a sinful disgrace of human privacy.
Amen to that.
OT: Sex in films is never pointless, every sex scene shows an intricate relationship between two people, the type of sex scene defines the emotions linked with it.
...And not to that.
First off, "meaning" is an entirely subjective term. What has meaning to you might carry none at all to others.
Secondly, the fact that something is generally attributed to carry great meaning doesn't entail that it always and inherently does so. Take music for instance; The fact that it's generally considered a way of artistic expression doesn't entail that every last elevator jingle or wailing drunkard is so.
Likewise, that sex is generally associated with strong emotions and bonding doesn't mean that Ilse und Günther do so the umpteenth time they're paid to have a go at each other before the camera; probably more bondage than bonding going on there.
So just as the fact that a scene contains sex doesn't make it meaningless-per-se, it doesn't make it meaningful-per-se either. That nature might have intended it also as a bonding device (except there's of course also the whole "spread-your-seed" instinct going on there) doesn't mean that function can't be dulled, professionalized, and commercialized, and it certainly doesn't mean that any such emotional entanglements will always carry through to the observers in any and all sex scenes.
So as (professionalized) sex isn't inherently "meaningful" (nothing subjective ever is), most big screen sex scenes don't even involve actual sex, and whatever meaning there might have been to it won't always translate well onto the big screen, proclaiming that all sex scenes are always meaningful is absurd.

What's more, it's satisfying to see a scene with impact when it comes to seeing a villain get comeuppance or the like, but it isn't satisfying to see the lead characters getting it on.
Not to you, anyway.
Others - by the looks of the box office counts many of them - might take a decidedly different view on what they find are satisfying and relevant elements and expositions to have in a story.
