When you're dealing with straight guys who are new to Gay 4 Pay, they are usually smiling. This isn't a smile because they are happy, though. You see, there are two types of smiles. The first, and most universal type of smile is that of nervousness. These guys know that in a few short minutes time, they will be interacting sexually with another male for the first time in their lives, and it scares the hell outta them. There are some that definitely look petrified, but most just smile a lot until they are inches away from another dude's cock, in which case fifty percent continue to smile. Now, by the same token, almost all the straight guys smile after they've cum. This is definitely happiness; not only because they have achieved an orgasm, but because they are about to receive a wad of cash and get the hell outta there.
