I’m okay with theories. If they work. When they no longer work it’s time to dispense with them. The number of theories out there attempting to explain away the vast array of orientations out there are just that: an attempt to invalidate them.
In the end what do you have? The same person who is or who has made a choice and who has the right to be just that.
This comes down to more than sexuality. It comes down to spirituality as well. In the end, you have the right to be who you are. Because that’s who you are. It just is!
