He probably will eventually, when he's older and fatter and needs money, but right now he's doing fine, so he doesn't have to. How many "tops" have we seen over the decades that eventually start doing things they used to never do. I remember in the 90's i really wanted to see Billy Brandt bottom, cause he had such a perfect ass, but it wasn't until he lost his looks that he finally did some bottoming scenes. and you could tell he hated it.
I do think Cody Cummings is really hot, just for the record. I think he's hoping he can transition into being a str8 porn star. I know he has done quite a few bi scenes.
I don't think he's even sucked a dick yet, has he?
