Personally I would do him if he doesn't have a big cock. I just want to suck on his 'ceps, abs, and pecs.
Supposedly the pic attached is of him but I haven't ever been able to find any other pics in the photo sets so I'm not entirely sure; it could be anyone. Plus I'm not convinced the pic has not been photoshopped.
Trouble posting the pic. Link here: http://www.lpsg.org/84220-john-cena.html#post1416618
