I found the so called "transition channel" to be a bit persuasive, perhaps encouraging,, which at the time I found it was actually helpful. But I would approach any source labelling itself as definitive information with at least a little skepticism.
Now the fun part. You might be bi gender AND gay which might make u double gay depending on your preference while identifying with either gender. Not trying to make it more confusing for you. on the contrary,, it might be more liberating to see that there are many possibilities and many happy "grey" areas into which one might fit or move between once one moves outside the binary. Either way,, happy discovery! You've come to the right place
