My thoughts are on this matter.

They don't make sense... the only two sexual orientations that make sense are Asexual and Pansexual.
Asexual makes sense now days because people are fucking evil and there's no need for all of humanity to reproduce now days; we have too many people as it is.
Pansexual makes sense because if you were to love someone, it should be for their mind, not for their body.
