Later-born males are more likely than first-borns to be gay, but only as bottoms, are as tops. Other evidence suggests that tops tend to be hyper-masculinized. Some people are born gay (meaning toward the gay side of the gay-straight spectrum), while other people choose to be gay (choosing to embrace same-sex relationships of any kind despite their place on the spectrum).

These include not only the obvious sex characteristics of the body but also less-observable traits such as the relative length of certain bones and specific brain structures, which can also be used to distinguish biological males from females. Scientists are just beginning to figure out how genetics and the environment interact to lead to certain traits.

Few aspects of human biology are as complex—or politically fraught—as sexual orientation.
