Sexual Orientation is a model invented by early LGBT activists and later adopted by scientists to classify people according to their attraction patterns with regard to reproductive sex. Science is an objective discipline that seeks to understand the real world. Done properly, it should be apolitical. Since sexuality is highly politicized in some places, unfortunately the facts about sexual orientation are often misconstrued by people with an unscientific agenda. So, here are the plain basic facts about sexual orientation.

There are three distinct orientations scientists use: heterosexual, homosexual, and bisexual. These orientations are not cultural phenomenon or identities but concrete facts about humans that have been tested in labs and confirmed as real.

  • Homosexual means “same sex attraction.” This term describes individuals who are exclusively attracted to members of the same biological sex.
  • Heterosexual means “different sex attraction.” This term describes individuals who are exclusively attracted to people who are not of the same sex as them.
  • Bisexual means “both same and different sex attraction.” The “bi” refers to a combination of the first two attraction patterns - homo and hetero. This term therefore describes anyone whose attractions aren’t exclusively limited to people of the same or other sex.
