Because this game is the master of technicalities, thats why, I admit, some of them actually caught me by surprise, they are pretty clever ways of using the setting.
In the real world you don't peak on your crush getting dicked, down, you don't read their thoughts fantasizing about having their organs getting rearranged, you don't find sex tapes of them etc. so find another 'real world' gotcha.
'I like doing it on top'
Since I hope we all have triple digits IQ, this tells us all the info we need to know about a LI's experience.
'This one time at band camp I was riding this guy and had 20 orgasms'
This game's choice of conveying the same type of info...
People don't need to hear in autistic details the LI's previous, or current sex life, or worse see it rendered and animated. And the author himself knows that because any excuse you can make is defeated by the existence of a safe mode. Bottom line its completely unnecessary information(unless making a cuck game

), and/or dev time, but we are past that, its clear at this point its an ego thing for the dev, hell it was clear even from inception in the dev thread when he was pondering adding the Parker birthday plot line.
