Don't know if you'd count him as "really thick", but saw Chris Stone in Baltimore recently (he lives there). Nice guy and looks great still. Has a goatee and longer hair than in his porn days. Had on a snug tank top and raggy/sexy jeans. He has a tight but not overly muscular body that looks fierce. GRRRRRRRRRR.
