I think it makes perfect sense for a pre-op to date men. She will eventually be a woman so if the desire is there to date a guy before surgery, so what? I also think (and don't stone me for saying this) that subconsciously the majority of men are curious about m 2 m sex. Being with a CD or someone that is pre-op lessens there own mind set of having sex with a guy, the same for the CD.
