Raiden, a character who was designed to appeal to females, running around naked is not a form of the camera lingering on sexual attributes? They even do sight gags where something gets in the way of Raiden's junk at the perfect time (which ends up drawing your eyes right to that area)
I think you said it all when you pointed out that it was done for a gag. Also I'd keep in mind Kojima's reaction to the fan response to Raiden was to put a gay character in MGS3 who looked exactly like him that you strip and trap in a locker.
