Wikipedia! Yeah, that'll show me!
Seriously, choose another source that isn't written by the majority of people who are biased and/or have no degree at all. Like a University or a licensed health research center or something.
Going to be against my own opinion about We pick who we are based on how we evolve Mentally, Morally, and how we use our curiosity to become better or worse people, Just a few seconds, if genetics WAS the actual reason why people have oddball loveuality.
you do know that genetics play a huge part in how the womb creates the person. I mean. It's a mixture between 50% sperm and %50 egg, Right? Then it changes based on the genetic Data and random selection. Which Does mean that genetics Do run all that in the womb.
If I am wrong, Once again, Please be somewhat Nice, and tell me where I am wrong.
If genetics were responsible for the loveual orientation of a person; everyone would either be (good majority of) heteroloveuals and (very few) biloveuals. Natural selection would be in favor of those who were able to pass on the loveual orientation gene.
However it doesn't work like that. Homoloveuality and Biloveuality has been around since the dawn of mankind and even animals.
And if a person chose their loveuality, they would've woke up someday and said to themselves "Hmm, maybe I'll go about my life sticking it in my own gender" or "Hmm, maybe I'll go stick it in a girl's vagoo." or both. People confuse with choosing your orientation and discovering your orientation. When you "choose" your loveual orientation; you actually discover that you have that orientation and that you've had it ever since you were nothing but a small bit of organic matter. You just never knew until now.
Because I know myself more than anyone else, and nowhere in my entire life do I ever recall that stopped to think to myself, "Hey, I'm going to be a person that likes to have loveual relationships & loveual contact with women for the rest of my life," and suddenly become a heteroloveual.
