I realize this is all quite inconsequential in the scheme of things, and I'm going on with this for way too long, but that's pretty much a non-sequitur. Let me explain.
The person you quoted expressed the issue of the penis only going up to the sternum during penetration, when it's shown to be much larger in interactions outside of penetration. It should've gone all the way through when balls deep according to shintopu. The issue wasn't the penis size, bulging, and lack of consequences of intercourse with such a large penis.
So when you then reply that you're not here for realism (paraphrasing of course), I then assumed it was about the lack of ATWT. And that had me scratching my head because ATWT is nowhere near realistic.
