Testosterones decide the sexuality

 

Into the internet age, many people still do not what cause the sexuality of a person. 

They, the medical doctors still want to find out whether it is because of DNA to cause the homosexuality.

We would like to advise the researcher, do not waste the time and money searching for DNA to prove that homosexuality cannot be cured to satisfy the religion leaders.

Just look at the fingers of men and women, you know their sexuality via the testosterone. 

Even the researchers are not way out of the fingers of bisexual, homosexual.
