Could it be possible that the people who engage in homosexual sex in prison are partly bisexual?

What do you think is more likely, that bisexuals are much more likely to commit crimes and spend time in prison than heterosexuals? or that heterosexuals can acquire a secondary sexual attraction?

I think it's a no-brainer. Even if we go beyond prison populations and study other situations in which situational homosexuality occurs, we still come to the conclusion that acquiring a secondary sexual attraction is possible. Such phenomena has not only been observed in prison populations and in other situations where the preferred partner is not available, but also in societies where such things are the norm (read up on the Sambia culture for another example of situational homosexuality; or in this case, situational pedophilia for the adult and situational homosexuality for the boy).
