As a country boy/kid, I can honestly say I had absolutely no concept of the nature of sexuality in general, men or women.
Now I recognize it as the least well understand aspect of science.
Men = Mars.
Women = Venus.
Given the fact there can often be relatability issues between the two planets, I believe it can sometimes lend itself to their inhabitants looking to their co-inhabitants for companionship etc.
Let me skip the essay and start initially with responding to others opinions on this matter?
Just FYI I myself am exclusively heterosexual.
