The subject must have been done to death, but if the long term regulars can bear with us, perhaps we could comment on a couple of points.
Never taken the plunge personally, but most guys seem to have thought about transexuals, with only a small minority taking it any further.
I knew a guy who had been in prison, and he confirmed that the majority of the cons who were in for longish terms would turn gay. He also mentioned that most of the 'bottoms' that he had experienced, did not get an erection with a penis in their anus, and only the confirmed gay boys would ever kiss.
But it does seem that a tranny, even a gorgeous one as some of them are, would not work for us folks who adore girls!
