From watching his videos on NVG I never realize he looked like "that", kinda funny. He was a good change of pace from that other white guy they used with the pencil dick but unfortunately Matt couldn't fuck. I wouldn't be surprised if straight sites weren't hiring him and he didn't feel like going gay for pay.
He had some good scenes (Cherie Deville & Ashley for Bangbros, Tia Cyrus for mommyblowsbest & Saya Song) but he did have some vids where he struggled to stay hard especially his lone Brazzers video where between his inability to keep it up and Brianna Banks' stink attitude throughout the scene, it totally killed it (in a bad way). He has a bad score on Brazzers because of it as well (he has more dislikes than likes)

but given his huge girth I think his few hiccups could be overlooked by most porn companies so I think the reason he hasn't been around has to do with his identity (he's been trying super hard for family/friends to not find out he's in porn hence why he has little social media presence). I actually did some digging and found his IG and twitter but they are both under his real name and given him trying to keep a low profile I wont share. (there's nothing much to see there anyway, he barely posts).
