The finger length predicts your sexuality says Dr. Tuesday Watts from UK

Your finger length could explain your sexual orientation according to a study. It says those with a big difference between their ring finger and index finger are more likely to be a gay.

Researchers say ginger length and sexuality are both linked to testosterone exposure in the womb.

Babies exposed to higher levels of the Male sex hormone have a greater chance of being homosexual..

And their index and ring finger are also more likely to be different lengths.

The study involved identical twins -18 pairs of women and 14 of men, where one in each set was straight.

Dr. Tuesday watts from The University of Essex said because identical twins, who share 100 percent of their genes, can differ in their sexual orientations, factors other than genetics must account for the differences. Research suggest that sexuality is determined in the womb.

It is dependent on the account of Male hormone we are exposed to or the way our individual bodies react to that hormone, with those exposed to higher levels being more likely to be bisexual or homosexual.
