I love this show! I can't wait for season 3!
A few quick things:
I'm glad DC said no. I don't get the story or comedic value of seeing Batman performing that act. At best it comes across as being edgy or shocking just for edginess's sake and then it becomes a meme that exists forever on the internet. A few years back there was some hubbub about a rooftop sex scene between Batman and Catwoman in a Judd Winick's New 52 Catwoman issue and it seemed more people, or at least a vocal group, were against that, and now it seems like the opposite, and that was only a handful of years and what accounts for that difference? I've seen both Harley Quinn seasons and the series has enough in your face, rude and crude, humor as it is. The Bat/Cat scene would've done nothing more than just been a sight gag.
I remember seeing that New 52 and being horrified. Not because of the sex, but because of the
sexism - it was all about Catwoman's T&A. There is a line between sexy and sexist - walk down Artist's Alley at any Con. Between that and turning Starfire into a bimbo, I chose to not read any of the New 52 stuff.
Most of these characters have sex in the comics. I've been reading Tom King's run, and Bruce and Selina are having sex pretty much as often as you'd expect two very fit people in love to be having it. Maybe more.

Depending on the specific scene, it's sexy, or funny, or sweet, etc. Just like real life.
Even as a kid, it was pretty easy to figure out that certain characters were hooking up. But with the advent of the direct sales market, comics for an older audience were more available from the Big Two.
The New Teen Titans #1 (1984) showed Dick & Kory waking up in bed together and obviously naked. Oh, the hullabaloo! I seem to remember George Perez commenting, "I don't know what you were doing when you were 19, but I was having sex!"
Pre-New 52, Damian's original origin was that he was artificially grown from DNA of Talia and Bruce, which was Talia's doing. Post New 52, all I can find is that he was born of Bruce and Talia having a "fling", seemingly consensual, with Talia getting pregnant but not telling Bruce. I'd say its unlikely that Talia date raped Bruce to get pregnant, both the original origin and it happening just during one of their times together makes more sense to me, but DC is pretty grimdark right now so that may be either a third origin or a "reveal" related to his second.
It's weirder than that. Back in 1987, Mike W. Barr and Jerry Bingham did a graphic novel called
Batman: Son of the Demon. In it, Talia and Bats are married by Ra's (only her consent was required) and nookie ensues. Talia gets pregnant, Bats gets protective and risk-averse, Talia lies and says she miscarries, the marriage is dissolved, a boy is born and adopted out. This was
never intended to be in canon. But writers have used bits inspired by it all over the place.
Fast forward to 2006, and Grant Morrison creates Damian and ties it in to said non-canon graphic novel.
Clear as mud?
