Not a satisfactory explanation. I've seen no refutation of hormonal imbalances. In the study of identical twins, why on some occasions is one twin hetero and one homo? Why would one twin choose homosexuality over heterosexuality?

Just saying one decided to get into weird sex doesn't explain it. Hormonal imbalance sounds best. Good day to you sir.

Keep in mind that if it’s hormonal -and the studies on that angle are far more contradictory- both fetuses would be exposed in twins.

Good day to you too.
