That's a distinction without meaning.

Pedophilia of young boys (or trysts with teenage boys) is always rooted in homosexuality -- or if you like, same sex attraction.

Heterosexual men are simply not attracted to young boys.  The only set of men who are attracted to boys are homosexual men.

Some here seem to be arguing that the priests who molested boys were all straight men.   And these straight men somehow developed a strange psychological condition that made them consumed with lust for boys.

I say no to that silly idea.   We have to first admit that the priests who molested all these thousands of  boys were homosexuals.
