Instead of guessing, here are some statistics. Anyone is welcome to post additional statistics:

http://en.wikipedia.org/wiki/Demogra...al_orientation

  • US (2011): 3.5% gay or bi, which leaves 97.5% hetero. Percentage of total pop that is TG = .3%.

  • UK (2010): 1% gay, .5% bi, which leaves 98.5% hetero (with 3% "don't know").

  • Australia (2003): 2% gay, 1% bi, 97% hetero (with 8% bi curious).

  • Canada (2003): 1% gay, 1% bi, which leaves 98% hetero.

  • Denmark (1992): 3% gay or bi, which leaves 97% hetero.

  • France (1992): 4% gay or bi (at least one experience), which leaves 96% hetero.

  • Norway (1998): 3% gay or bi (at least one experience), which leaves 97% hetero.

I really find it hard to believe that as much as 50% CDs would be gay or bi based on these figures, especially since sexual orientation has nothing to do with gender ID. Even if you double the above gay/bi statistics to apply to TGs, it would still mean that over 90% of TGs are hetero.
