Time takes its toll, as does bodybuilding (chemical or not). Jake's a real people pleaser, so long as the cash keeps flowing. He had some real chemistry early on in his Gayhoopla days, particularly in the couple of shows he did with his RL friend who went by the name John Bailey (Jake was Tyler Hanson back then, of course). They were football buddies in high school, apparently, and had that sort of friendly chemistry. John disappeared after a couple of shows (joined the Navy, as far as I know), and Jake did some more "traditional" gay vids before having a falling out with Gayhoopla. He claimed they screwed him out of some $$$, but I don't know if it's true or not. I know that they were frustrated with him because he went ahead and fucked John during their first video chat (much to the delight of the audience, but they weren't at all experienced or prepared, and John was clearly suffering as a result). I think GH was a bit alarmed that they'd gone there so readily (GH didn't make anything from it, the video chats were 100% model tips, and they did rather well).
Anyway, yes, I agree with you, though I have to admit something of a bias against (IMHO) overly-developed guys. Jake looked much better to me as a twunk. Actually I thought John was the more attractive of the two, but it was clear he'd have never gotten into things without Jake around.
