Get to FL often? If you have the control to stay JUST under rock hard when you're putting it down a throat I got someone well trained for you.
He can go for hours, begging for more, harder, deeper, leave it in longer please sir. Here's a small clip of his last trip to see me just for this.
Heaven

This is why I stay just short of rock hard when I'm going down someone's throat. Just slightly floppy, bends perfectly down the throat like it was made to fit in guys necks.
(Rock hard for pounding ass though 😏)
Example.
Still might need to pick up that dildo tho. Training and practice can't hurt

I like to watch my dick getting sucked from soft to mostly hard. I try to hold my junk at just below rock hard for oral. Bends down the throat easier and nicely that way. But still fat and long.
Example..
Keeps the ones that are good at swallowing it coming back over and over for years. 😏😉🍆😂
