Homosexuality may help us bond, experts say

25 noviembre 2014

Homosexual behavior may have evolved to promote social bonding in humans, according to new research. Researchers found that heterosexual women who have higher levels of progesterone are more likely to be open to the idea of engaging in sexual behaviour with other women. Similarly, when heterosexual men are subtly reminded of the importance of having male friends and allies, they report more positive attitudes toward engaging in sexual behaviour with other men. This pattern is particularly dramatic in men who have high levels of progesterone.
