Does he have armpit contents? Or like contents that is dedicated to his armpits?
It's been a bit since I subscribed, so someone please correct me if things have changed...
Johnny us a definite DILF, but his OF is pretty mainstream and heterormative. Most of his stuff is pretty standard B/G stuff.
There may be the occasional vanity posts of him flexing or with his tongue out or smoking a cigar, but those seem to be the exception. There aren't even any solo vids to speak of, which are a staple for any main star.
I compare him to Oliver Flynn: Oliver is an up and coming star, and while also aggressively straight, he has a slightky broader variety of material, and is professional and always responsive to his DMs. (Though I will note he does tend to recycle material through his DMs, so something to watch for.)
