Perhaps Mark should merge the two sites and use BSB as the "undergraduate" prep school or training grounds for newbies, and then have them graduate to college dudes where they can earn their doctorates in all out gay professional porn.
I like your point of view. I would think it harder for a model who is lower on the Kinsey Scale to jump right into CD as the premise is not defined as "Straight" but the performances are without out a doubt all out "passionate gay sex." This is the expectation. The models, though very professional (in my opinion) perform even when it seems, they are struggling. I feel there are just as many, "more-straight" guys on CD as there are on BSB.
